.. _`Installation`:
Installation
============
Python & OS Support
-------------------
pip works with CPython versions 2.6, 2.7, 3.1, 3.2, 3.3, 3.4 and also pypy.
pip works on Unix/Linux, OS X, and Windows.
.. note::
Python 2.5 was supported through v1.3.1, and Python 2.4 was supported through v1.1.
.. _`get-pip`:
Install pip
-----------
To install or upgrade pip, securely download `get-pip.py
<https://bootstrap.pypa.io/get-pip.py>`_. [1]_
Then run the following (which may require administrator access)::
python get-pip.py
If `setuptools`_ (or `distribute`_) is not already installed, ``get-pip.py`` will
install `setuptools`_ for you. [2]_
To upgrade an existing `setuptools`_ (or `distribute`_), run ``pip install -U setuptools`` [3]_
Upgrade pip
-----------
On Linux or OS X:
::
pip install -U pip
On Windows [4]_:
::
python -m pip install -U pip
Using Package Managers
----------------------
On Linux, pip will generally be available for the system install of python using
the system package manager, although often the latest version will be
unavailable.
On Debian and Ubuntu::
sudo apt-get install python-pip
On Fedora::
sudo yum install python-pip

.. [1] "Secure" in this context means using a modern browser or a
tool like `curl` that verifies SSL certificates when downloading from
https URLs.
.. [2] Beginning with pip v1.5.1, ``get-pip.py`` stopped requiring setuptools to
be installed first.
.. [3] Although using ``pip install --upgrade setuptools`` to upgrade from
distribute to setuptools works in isolation, it's possible to get
"ImportError: No module named setuptools" when using pip<1.4 to upgrade a
package that depends on setuptools or distribute. See :doc:`here for
details <distribute_setuptools>`.
