Virtual Environments
----------
After Setuptools & Pip, the next development tool that you should install is
`virtualenv <http://pypi.python.org/pypi/virtualenv/>`_. Use pip
A Virtual Environment is a tool to keep the dependencies required by different projects
in separate places, by creating virtual Python environments for them. It solves the
"Project X depends on version 1.x but, Project Y needs 4.x" dilemma, and keeps
your global site-packages directory clean and manageable.
.. code-block:: console
For example, you can work on a project which requires Django 1.3 while also
maintaining a project which requires Django 1.0.
$ pip install virtualenv
The virtualenv kit provides the ability to create virtual Python environments
that do not interfere with either each other, or the main Python installation.
If you install virtualenv before you begin coding then you can get into the
habit of using it to create completely clean Python environments for each
project. This is particularly important for Web development, where each
framework and application will have many dependencies.
To set up a new Python environment, change the working directory to where ever
you want to store the environment, and run the virtualenv utility in your
project's directory
.. code-block:: console
$ virtualenv venv
To use an environment, run ``source venv/bin/activate``. Your command prompt
will change to show the active environment. Once you have finished working in
the current virtual environment, run ``deactivate`` to restore your settings
to normal.
Each new environment automatically includes a copy of ``pip``, so that you can
setup the third-party libraries and tools that you want to use in that
environment. Put your own code within a subdirectory of the environment,
however you wish. When you no longer need a particular environment, simply
copy your code out of it, and then delete the main directory for the environment.
To start using and see more information: `Virtual Environments <http://github.com/kennethreitz/python-guide/blob/master/docs/dev/virtualenvs.rst>`_ docs.
