Installation
|
|
============
|
|
|
|
Python & OS Support
|
|
-------------------
|
|
|
|
pip works with CPython versions 2.6, 2.7, 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.
|
|
|
|
pip included with Python
|
|
------------------------
|
|
Python 2.7.9 and later (on the python2 series), and Python 3.4
|
|
and later include pip by default [1]_, so you may have pip already.
|
|
|
|
.. _`get-pip`:
|
|
|
|
Install pip
|
|
-----------
|
|
|
|
To install pip, securely download `get-pip.py
|
|
<https://bootstrap.pypa.io/get-pip.py>`_. [2]_
|
|
|
|
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. [3]_
|
|
|
|
To upgrade an existing `setuptools`_ (or `distribute`_), run ``pip install -U
|
|
setuptools``. [4]_
|
|
|
|
Additionally, ``get-pip.py`` supports using the :ref:`pip install options <pip
|
|
install Options>` and the :ref:`general options <General Options>`. Below are
|
|
some examples:
|
|
|
|
Install from local copies of pip and setuptools::
|
|
|
|
python get-pip.py --no-index --find-links=/local/copies
|
|
|
|
Install to the user site [5]_::
|
|
|
|
python get-pip.py --user
|
|
|
|
Install behind a proxy::
|
|
|
|
python get-pip.py --proxy="[user:passwd@]proxy.server:port"
|
|
|
|
|
|
Upgrade pip
|
|
-----------
|
|
|
|
On Linux or OS X:
|
|
|
|
::
|
|
|
|
pip install -U pip
|
|
|
|
|
|
On Windows [6]_:
|
|
|
|
::
|
|
|
|
python -m pip install -U pip
|
|
|
|
|
|
|
|
Using OS 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
|
|
|

|
.. [2] "Secure" in this context means using a modern browser or a
|
|
tool like `curl` that verifies SSL certificates when downloading from
|
|
https URLs.
|
|
|
|
.. [3] Beginning with pip v1.5.1, ``get-pip.py`` stopped requiring setuptools to
|
|
be installed first.
|
|
|
|
.. [4] 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>`.
|
|
|
|
.. [5] The pip developers are considering making ``--user`` the default for all
|
|
installs, including ``get-pip.py`` installs of pip, but at this time,
|
|
``--user`` installs for pip itself, should not be considered to be fully
|
|
tested or endorsed. For discussion, see `Issue 1668
|
|
<https://github.com/pypa/pip/issues/1668>`_.
