FAQ: Installation
|
|
=================
|
|
|
|
How do I get started?
|
|
---------------------
|
|
|
|
#. `Download the code`_.
|
|
#. Install Django (read the :doc:`installation guide </intro/install>`).
|
|
#. Walk through the :doc:`tutorial </intro/tutorial01>`.
|
|
#. Check out the rest of the :doc:`documentation </index>`, and `ask questions`_ if you
|
|
run into trouble.

What are Django's prerequisites?
|
|
--------------------------------
|
|
|
|
Django requires Python, specifically Python 2.6.5 - 2.7.x. No other Python
|
|
libraries are required for basic Django usage. Django 1.5 also has
|
|
experimental support for Python 3.2.3 and above.
|
|
|
|
For a development environment -- if you just want to experiment with Django --
|
|
you don't need to have a separate Web server installed; Django comes with its
|
|
own lightweight development server. For a production environment, Django follows
|
|
the WSGI spec, :pep:`3333`, which means it can run on a variety of server
|
|
platforms. See :doc:`Deploying Django </howto/deployment/index>` for some
|
|
popular alternatives. Also, the `server arrangements wiki page`_ contains
|
|
details for several deployment strategies.
|
|
|
|
If you want to use Django with a database, which is probably the case, you'll
|
|
also need a database engine. PostgreSQL_ is recommended, because we're
|
|
PostgreSQL fans, and MySQL_, `SQLite 3`_, and Oracle_ are also supported.

|
Do I lose anything by using Python 2.6 versus newer Python versions, such as Python 2.7?
|
|
----------------------------------------------------------------------------------------
|
|
|
|
Not in the core framework. Currently, Django itself officially supports
|
|
Python 2.6 (2.6.5 or higher) and 2.7. However, newer versions of
|
|
Python are often faster, have more features, and are better supported. If you
|
|
use a newer version of Python you will also have access to some APIs that
|
|
aren't available under older versions of Python.
|
|
|
|
Third-party applications for use with Django are, of course, free to set their
|
|
own version requirements.
|
|
|
|
All else being equal, we recommend that you use the latest 2.x release
|
|
(currently Python 2.7). This will let you take advantage of the numerous
|
|
improvements and optimizations to the Python language since version 2.6.
|
|
|
|
Generally speaking, we don't recommend running Django on Python 3 yet; see
|
|
below for more.

Can I use Django with Python 3?
|
|
-------------------------------
|
|
|
|
Django 1.5 introduces experimental support for Python 3.2.3 and above. However,
|
|
we don't yet suggest that you use Django and Python 3 in production.
|
|
|
|
Python 3 support should be considered a "preview". It's offered to bootstrap
|
|
the transition of the Django ecosystem to Python 3, and to help you start
|
|
porting your apps for future Python 3 compatibility. But we're not yet
|
|
confident enough to promise stability in production.
|
|
|
|
Our current plan is to make Django 1.6 suitable for general use with Python 3.
|
|
|
|
Will Django run under shared hosting (like TextDrive or Dreamhost)?
|
|
-------------------------------------------------------------------
|
|
|
|
See our `Django-friendly Web hosts`_ page.

|
|
|
|
Should I use the stable version or development version?
|
|
-------------------------------------------------------
|
|
|
|
Generally, if you're using code in production, you should be using a
|
|
stable release. The Django project publishes a full stable release
|
|
every nine months or so, with bugfix updates in between. These stable
|
|
releases contain the API that is covered by our backwards
|
|
compatibility guarantees; if you write code against stable releases,
|
|
you shouldn't have any problems upgrading when the next official
|
|
version is released.
