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 any version of Python from 2.4

through 2.7. 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, 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 2.4 versus newer Python versions, such as Python 2.5 or 2.6?

-----------------------------------------------------------------------------------------------

Not in the core framework. Currently, Django itself officially supports any

version of Python from 2.4 through 2.7, inclusive. However, newer versions of

Python are often faster, have more features, and are better supported.

Third-party applications for use with Django are, of course, free to set their

own version requirements.

Over the next year or two Django will begin dropping support for older Python

versions as part of a migration which will end with Django running on Python 3

(see below for details).

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 2.4, and

will help ease the process of dropping support for older Python versions on

the road to Python 3.

Can I use Django with Python 2.3?

---------------------------------

Django 1.1 (and earlier) supported Python 2.3. Django 1.2 and newer does not.

We highly recommend you upgrade Python if at all possible, but Django 1.1 will

continue to work on Python 2.3.

Can I use Django with Python 3?

-------------------------------

Not at the moment. Python 3.0 introduced a number of

backwards-incompatible changes to the Python language, and although

these changes are generally a good thing for Python's future, it will

be a while before most Python software catches up and is able to run

on Python 3.0. For larger Python-based software like Django, the

transition is expected to take at least a year or two (since it

involves dropping support for older Python releases and so must be

done gradually).

In the meantime, Python 2.x releases will be supported and provided

with bug fixes and security updates by the Python development team, so

continuing to use a Python 2.x release during the transition should

not present any risk.

Will Django run under shared hosting (like TextDrive or Dreamhost)?

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.
