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 2.7 or 3.2 and above. No other
|
|
Python libraries are required for basic Django usage.
|
|
|
|
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.

What Python version can I use with Django?
|
|
------------------------------------------
|
|
|
|
============== ===============
|
|
Django version Python versions
|
|
============== ===============
|
|
1.4 2.5, 2.6, 2.7
|
|
1.5 2.6, 2.7 and 3.2, 3.3 (experimental)
|
|
1.6 2.6, 2.7 and 3.2, 3.3
|
|
**1.7** **2.7** and **3.2, 3.3, 3.4**
|
|
============== ===============
|
|
|
|
For a given series of Python versions, only the latest release is officially
|
|
supported. For instance, at the time of writing (April 1st, 2014), the latest
|
|
release in the 2.7 series is 2.7.6.
|
|
|
|
What Python version should I use with Django?
|
|
---------------------------------------------
|
|
|
|
As of Django 1.6, Python 3 support is considered stable and you can safely use
|
|
it in production. See also :doc:`/topics/python3`. However, the community is
|
|
still in the process of migrating third-party packages and applications to
|
|
Python 3.
|
|
|
|
If you're starting a new project, and the dependencies you plan to use work on
|
|
Python 3, you should use Python 3. If they don't, consider contributing to the
|
|
porting efforts, or stick to Python 2.
|
|
|
|
Since newer versions of Python are often faster, have more features, and are
|
|
better supported, all else being equal, we recommend that you use the latest
|
|
2.x.y or 3.x.y release.
|
|
|
|
You don't lose anything in Django by using an older release, but you don't take
|
|
advantage of the improvements and optimizations in newer Python releases.
|
|
Third-party applications for use with Django are, of course, free to set their
|
|
own version requirements.
|
|
|
|
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.
