## Global
#### [`cache-dir`](#cache-dir) {: #cache-dir }
Path to the cache directory.
Defaults to `$HOME/Library/Caches/uv` on macOS, `$XDG_CACHE_HOME/uv` or `$HOME/.cache/uv` on
Linux, and `%LOCALAPPDATA%\uv\cache` on Windows.
**Default value**: `None`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv]
cache-dir = "./.uv_cache"
```
=== "uv.toml"
```toml
cache-dir = "./.uv_cache"
```
---
#### [`compile-bytecode`](#compile-bytecode) {: #compile-bytecode }
Compile Python files to bytecode after installation.
By default, uv does not compile Python (`.py`) files to bytecode (`__pycache__/*.pyc`);
instead, compilation is performed lazily the first time a module is imported. For use-cases
in which start time is critical, such as CLI applications and Docker containers, this option
can be enabled to trade longer installation times for faster start times.
When enabled, uv will process the entire site-packages directory (including packages that
are not being modified by the current operation) for consistency. Like pip, it will also
ignore errors.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv]
compile-bytecode = true
```
=== "uv.toml"
```toml
compile-bytecode = true
```
---

=== "pyproject.toml"
```toml
[tool.uv]
dev-dependencies = ["ruff==0.5.0"]
```
=== "uv.toml"
```toml
dev-dependencies = ["ruff==0.5.0"]
```
---
#### [`environments`](#environments) {: #environments }
A list of supported environments against which to resolve dependencies.
By default, uv will resolve for all possible environments during a `uv lock` operation.
However, you can restrict the set of supported environments to improve performance and avoid
unsatisfiable branches in the solution space.
**Default value**: `[]`
**Type**: `str | list[str]`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv]
# Resolve for macOS, but not for Linux or Windows.
environments = ["sys_platform == 'darwin'"]
```
=== "uv.toml"

environments = ["sys_platform == 'darwin'"]
```
---
#### [`exclude-newer`](#exclude-newer) {: #exclude-newer }

```
---
#### [`extra-index-url`](#extra-index-url) {: #extra-index-url }
Extra URLs of package indexes to use, in addition to `--index-url`.
Accepts either a repository compliant with [PEP 503](https://peps.python.org/pep-0503/)
(the simple repository API), or a local directory laid out in the same format.
All indexes provided via this flag take priority over the index specified by
[`index_url`](#index-url). When multiple indexes are provided, earlier values take priority.
To control uv's resolution strategy when multiple indexes are present, see
[`index_strategy`](#index-strategy).
**Default value**: `[]`
**Type**: `list[str]`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv]
extra-index-url = ["https://download.pytorch.org/whl/cpu"]

```toml
extra-index-url = ["https://download.pytorch.org/whl/cpu"]
```
---
#### [`find-links`](#find-links) {: #find-links }
Locations to search for candidate distributions, in addition to those found in the registry
indexes.
If a path, the target must be a directory that contains packages as wheel files (`.whl`) or
source distributions (`.tar.gz` or `.zip`) at the top level.
If a URL, the page must contain a flat list of links to package files adhering to the
formats described above.
**Default value**: `[]`
**Type**: `list[str]`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv]
find-links = ["https://download.pytorch.org/whl/torch_stable.html"]

=== "uv.toml"
```toml
find-links = ["https://download.pytorch.org/whl/torch_stable.html"]
```
---
#### [`index-strategy`](#index-strategy) {: #index-strategy }
The strategy to use when resolving against multiple index URLs.
By default, uv will stop at the first index on which a given package is available, and
limit resolutions to those present on that first index (`first-match`). This prevents
"dependency confusion" attacks, whereby an attack can upload a malicious package under the
same name to a secondary.
**Default value**: `"first-index"`
**Possible values**:
- `"first-index"`: Only use results from the first index that returns a match for a given package name
- `"unsafe-first-match"`: Search for every package name across all indexes, exhausting the versions from the first index before moving on to the next
- `"unsafe-best-match"`: Search for every package name across all indexes, preferring the "best" version found. If a package version is in multiple indexes, only look at the entry for the first index
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv]
index-strategy = "unsafe-best-match"
```
=== "uv.toml"
```toml
index-strategy = "unsafe-best-match"
```
---
#### [`index-url`](#index-url) {: #index-url }
The URL of the Python package index (by default: <https://pypi.org/simple>).
Accepts either a repository compliant with [PEP 503](https://peps.python.org/pep-0503/)
(the simple repository API), or a local directory laid out in the same format.
The index provided by this setting is given lower priority than any indexes specified via
[`extra_index_url`](#extra-index-url).
**Default value**: `"https://pypi.org/simple"`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv]
index-url = "https://test.pypi.org/simple"
```
=== "uv.toml"
```toml
index-url = "https://test.pypi.org/simple"
```
---
#### [`keyring-provider`](#keyring-provider) {: #keyring-provider }
Attempt to use `keyring` for authentication for index URLs.
At present, only `--keyring-provider subprocess` is supported, which configures uv to
use the `keyring` CLI to handle authentication.
**Default value**: `"disabled"`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv]
keyring-provider = "subprocess"
```
=== "uv.toml"
```toml
keyring-provider = "subprocess"
```
---
#### [`link-mode`](#link-mode) {: #link-mode }
The method to use when installing packages from the global cache.

```toml
[tool.uv]
managed = false
```
=== "uv.toml"
```toml
managed = false
```
---
#### [`native-tls`](#native-tls) {: #native-tls }
Whether to load TLS certificates from the platform's native certificate store.
By default, uv loads certificates from the bundled `webpki-roots` crate. The
`webpki-roots` are a reliable set of trust roots from Mozilla, and including them in uv
improves portability and performance (especially on macOS).
However, in some cases, you may want to use the platform's native certificate store,
especially if you're relying on a corporate trust root (e.g., for a mandatory proxy) that's
included in your system's certificate store.
**Default value**: `false`

<span id="emit-marker-expression"></span>
Whether to emit a marker string indicating the conditions under which the set of pinned
dependencies is valid.
The pinned dependencies may be valid even when the marker expression is
false, but when the expression is true, the requirements are known to
be correct.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
emit-marker-expression = true

<span id="extra-index-url"></span>
Extra URLs of package indexes to use, in addition to `--index-url`.
Accepts either a repository compliant with [PEP 503](https://peps.python.org/pep-0503/)
(the simple repository API), or a local directory laid out in the same format.
All indexes provided via this flag take priority over the index specified by
[`index_url`](#index-url). When multiple indexes are provided, earlier values take priority.
To control uv's resolution strategy when multiple indexes are present, see
[`index_strategy`](#index-strategy).
**Default value**: `[]`
**Type**: `list[str]`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
extra-index-url = ["https://download.pytorch.org/whl/cpu"]
```

```toml
[pip]
extra-index-url = ["https://download.pytorch.org/whl/cpu"]
```
---
#### [`find-links`](#pip_find-links) {: #pip_find-links }
<span id="find-links"></span>
Locations to search for candidate distributions, in addition to those found in the registry
indexes.
If a path, the target must be a directory that contains packages as wheel files (`.whl`) or
source distributions (`.tar.gz` or `.zip`) at the top level.
If a URL, the page must contain a flat list of links to package files adhering to the
formats described above.
**Default value**: `[]`

```toml
[pip]
generate-hashes = true
```
---
#### [`index-strategy`](#pip_index-strategy) {: #pip_index-strategy }
<span id="index-strategy"></span>
The strategy to use when resolving against multiple index URLs.
By default, uv will stop at the first index on which a given package is available, and
limit resolutions to those present on that first index (`first-match`). This prevents
"dependency confusion" attacks, whereby an attack can upload a malicious package under the
same name to a secondary.
**Default value**: `"first-index"`
**Possible values**:
- `"first-index"`: Only use results from the first index that returns a match for a given package name
- `"unsafe-first-match"`: Search for every package name across all indexes, exhausting the versions from the first index before moving on to the next
- `"unsafe-best-match"`: Search for every package name across all indexes, preferring the "best" version found. If a package version is in multiple indexes, only look at the entry for the first index
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
index-strategy = "unsafe-best-match"
```
=== "uv.toml"
```toml
[pip]
index-strategy = "unsafe-best-match"
```
---
#### [`index-url`](#pip_index-url) {: #pip_index-url }

The URL of the Python package index (by default: <https://pypi.org/simple>).
Accepts either a repository compliant with [PEP 503](https://peps.python.org/pep-0503/)
(the simple repository API), or a local directory laid out in the same format.
The index provided by this setting is given lower priority than any indexes specified via
[`extra_index_url`](#extra-index-url).
**Default value**: `"https://pypi.org/simple"`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
index-url = "https://test.pypi.org/simple"
```
=== "uv.toml"
```toml
[pip]
index-url = "https://test.pypi.org/simple"
```
---
#### [`keyring-provider`](#pip_keyring-provider) {: #pip_keyring-provider }
<span id="keyring-provider"></span>
Attempt to use `keyring` for authentication for index URLs.
At present, only `--keyring-provider subprocess` is supported, which configures uv to
use the `keyring` CLI to handle authentication.
**Default value**: `disabled`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
keyring-provider = "subprocess"
```
=== "uv.toml"
```toml
[pip]
keyring-provider = "subprocess"
```

---
#### [`no-build`](#pip_no-build) {: #pip_no-build }
<span id="no-build"></span>
Don't build source distributions.
When enabled, resolving will not run arbitrary Python code. The cached wheels of
already-built source distributions will be reused, but operations that require building
distributions will exit with an error.
Alias for `--only-binary :all:`.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
no-build = true
```
=== "uv.toml"
```toml
[pip]
no-build = true
```
---

=== "uv.toml"
```toml
[pip]
no-build-isolation-package = ["package1", "package2"]
```
---
#### [`no-deps`](#pip_no-deps) {: #pip_no-deps }
<span id="no-deps"></span>
Ignore package dependencies, instead only add those packages explicitly listed
on the command line to the resulting the requirements file.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]

included in the resolution. Equivalent to pip-compile's `--unsafe-package` option.
**Default value**: `[]`
**Type**: `list[str]`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
no-emit-package = ["ruff"]
```

no-index = true
```
---
#### [`no-sources`](#pip_no-sources) {: #pip_no-sources }
<span id="no-sources"></span>
Ignore the `tool.uv.sources` table when resolving dependencies. Used to lock against the
standards-compliant, publishable package metadata, as opposed to using any local or Git
sources.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
no-sources = true
```
=== "uv.toml"
```toml
[pip]
no-sources = true
```
---
#### [`no-strip-extras`](#pip_no-strip-extras) {: #pip_no-strip-extras }
<span id="no-strip-extras"></span>
Include extras in the output file.
By default, uv strips extras, as any packages pulled in by the extras are already included
as dependencies in the output file directly. Further, output files generated with
`--no-strip-extras` cannot be used as constraints files in `install` and `sync` invocations.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
no-strip-extras = true
```
=== "uv.toml"
```toml
[pip]
no-strip-extras = true
```
---
#### [`no-strip-markers`](#pip_no-strip-markers) {: #pip_no-strip-markers }
<span id="no-strip-markers"></span>
Include environment markers in the output file generated by `uv pip compile`.
By default, uv strips environment markers, as the resolution generated by `compile` is
only guaranteed to be correct for the target environment.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
no-strip-markers = true
```
=== "uv.toml"
```toml
[pip]
no-strip-markers = true
```
---
#### [`only-binary`](#pip_only-binary) {: #pip_only-binary }
<span id="only-binary"></span>
Only use pre-built wheels; don't build source distributions.
When enabled, resolving will not run code from the given packages. The cached wheels of already-built
source distributions will be reused, but operations that require building distributions will
exit with an error.
Multiple packages may be provided. Disable binaries for all packages with `:all:`.
Clear previously specified packages with `:none:`.
**Default value**: `[]`
**Type**: `list[str]`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
only-binary = ["ruff"]
```
=== "uv.toml"
```toml
[pip]
only-binary = ["ruff"]
```
---
#### [`output-file`](#pip_output-file) {: #pip_output-file }
<span id="output-file"></span>
Write the requirements generated by `uv pip compile` to the given `requirements.txt` file.
If the file already exists, the existing versions will be preferred when resolving
dependencies, unless `--upgrade` is also specified.
**Default value**: `None`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
output-file = "requirements.txt"
```
=== "uv.toml"
```toml
[pip]
output-file = "requirements.txt"
```
---
#### [`prefix`](#pip_prefix) {: #pip_prefix }
<span id="prefix"></span>
Install packages into `lib`, `bin`, and other top-level folders under the specified
directory, as if a virtual environment were present at that location.
In general, prefer the use of `--python` to install into an alternate environment, as
scripts and other artifacts installed via `--prefix` will reference the installing
interpreter, rather than any interpreter added to the `--prefix` directory, rendering them
non-portable.
**Default value**: `None`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
prefix = "./prefix"
```
=== "uv.toml"
```toml
[pip]
prefix = "./prefix"
```
---
#### [`prerelease`](#pip_prerelease) {: #pip_prerelease }
<span id="prerelease"></span>
The strategy to use when considering pre-release versions.
By default, uv will accept pre-releases for packages that _only_ publish pre-releases,
along with first-party requirements that contain an explicit pre-release marker in the
declared specifiers (`if-necessary-or-explicit`).
**Default value**: `"if-necessary-or-explicit"`
**Possible values**:
- `"disallow"`: Disallow all pre-release versions
- `"allow"`: Allow all pre-release versions
- `"if-necessary"`: Allow pre-release versions if all versions of a package are pre-release
- `"explicit"`: Allow pre-release versions for first-party packages with explicit pre-release markers in their version requirements
- `"if-necessary-or-explicit"`: Allow pre-release versions if all versions of a package are pre-release, or if the package has an explicit pre-release marker in its version requirements
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
prerelease = "allow"
```
=== "uv.toml"
```toml
[pip]
prerelease = "allow"
```
---
#### [`python`](#pip_python) {: #pip_python }
<span id="python"></span>
The Python interpreter into which packages should be installed.
By default, uv installs into the virtual environment in the current working directory or
any parent directory. The `--python` option allows you to specify a different interpreter,
which is intended for use in continuous integration (CI) environments or other automated
workflows.
Supported formats:
- `3.10` looks for an installed Python 3.10 using `py --list-paths` on Windows, or
`python3.10` on Linux and macOS.
- `python3.10` or `python.exe` looks for a binary with the given name in `PATH`.
- `/home/ferris/.local/bin/python3.10` uses the exact Python at the given path.
**Default value**: `None`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
python = "3.10"
```
=== "uv.toml"
```toml
[pip]
python = "3.10"
```
---
#### [`python-platform`](#pip_python-platform) {: #pip_python-platform }
<span id="python-platform"></span>
The platform for which requirements should be resolved.
Represented as a "target triple", a string that describes the target platform in terms of
its CPU, vendor, and operating system name, like `x86_64-unknown-linux-gnu` or
`aaarch64-apple-darwin`.
**Default value**: `None`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
python-platform = "x86_64-unknown-linux-gnu"
```
=== "uv.toml"
```toml
[pip]

<span id="python-version"></span>
The minimum Python version that should be supported by the resolved requirements (e.g.,
`3.8` or `3.8.17`).
If a patch version is omitted, the minimum patch version is assumed. For example, `3.8` is
mapped to `3.8.0`.
**Default value**: `None`
**Type**: `str`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
python-version = "3.8"
```
=== "uv.toml"
```toml
[pip]
python-version = "3.8"
```
---
#### [`reinstall`](#pip_reinstall) {: #pip_reinstall }

```
=== "uv.toml"
```toml
[pip]
reinstall-package = ["ruff"]
```
---
#### [`require-hashes`](#pip_require-hashes) {: #pip_require-hashes }
<span id="require-hashes"></span>
Require a matching hash for each requirement.
Hash-checking mode is all or nothing. If enabled, _all_ requirements must be provided
with a corresponding hash or set of hashes. Additionally, if enabled, _all_ requirements
must either be pinned to exact versions (e.g., `==1.0.0`), or be specified via direct URL.
Hash-checking mode introduces a number of additional constraints:
- Git dependencies are not supported.
- Editable installs are not supported.
- Local dependencies are not supported, unless they point to a specific wheel (`.whl`) or
source archive (`.zip`, `.tar.gz`), as opposed to a directory.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
require-hashes = true
```
=== "uv.toml"

=== "pyproject.toml"
```toml
[tool.uv.pip]
resolution = "lowest-direct"
```
=== "uv.toml"
```toml
[pip]
resolution = "lowest-direct"
```
---
#### [`strict`](#pip_strict) {: #pip_strict }
<span id="strict"></span>
Validate the Python environment, to detect packages with missing dependencies and other
issues.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"

```
=== "uv.toml"
```toml
[pip]
strict = true
```
---
#### [`system`](#pip_system) {: #pip_system }
<span id="system"></span>
Install packages into the system Python environment.
By default, uv installs into the virtual environment in the current working directory or
any parent directory. The `--system` option instructs uv to instead use the first Python
found in the system `PATH`.
WARNING: `--system` is intended for use in continuous integration (CI) environments and
should be used with caution, as it can modify the system Python installation.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
system = true
```
=== "uv.toml"

**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
target = "./target"
```
=== "uv.toml"
```toml
[pip]
target = "./target"
```
---
#### [`universal`](#pip_universal) {: #pip_universal }
<span id="universal"></span>
Perform a universal resolution, attempting to generate a single `requirements.txt` output
file that is compatible with all operating systems, architectures, and Python
implementations.
In universal mode, the current Python version (or user-provided `--python-version`) will be
treated as a lower bound. For example, `--universal --python-version 3.7` would produce a
universal resolution for Python 3.7 and later.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
universal = true

upgrade-package = ["ruff"]
```
---
#### [`verify-hashes`](#pip_verify-hashes) {: #pip_verify-hashes }
<span id="verify-hashes"></span>
Validate any hashes provided in the requirements file.
Unlike `--require-hashes`, `--verify-hashes` does not require that all requirements have
hashes; instead, it will limit itself to verifying the hashes of those requirements that do
include them.
**Default value**: `false`
**Type**: `bool`
**Example usage**:
=== "pyproject.toml"
```toml
[tool.uv.pip]
verify-hashes = true
```
=== "uv.toml"
```toml
[pip]
verify-hashes = true
```
---
## `workspace`
#### [`exclude`](#workspace_exclude) {: #workspace_exclude }
<span id="exclude"></span>
