@ -504,6 +504,8 @@ uv accepts the following command-line arguments as environment variables:
uv will require that all dependencies have a hash specified in the requirements file.
- `UV_CONSTRAINT`: Equivalent to the `--constraint` command-line argument. If set, uv will use this
file as the constraints file. Uses space-separated list of files.
- `UV_LINK_MODE`: Equivalent to the `--link-mode` command-line argument. If set, uv will use this
as a link mode.
In each case, the corresponding command-line argument takes precedence over an environment variable.
