Prior to version 1.3, pip did not use SSL for downloading packages from PyPI, and thus left users more vulnerable to security threats. We advise installing at least version 1.3. If you’re using virtualenv to install pip, we advise installing at least version 1.9, which contains pip version 1.3.

Python & OS Support

pip works with CPython versions 2.5, 2.6, 2.7, 3.1, 3.2, 3.3 and also pypy.

pip works on Unix/Linux, OS X, and Windows.

Using virtualenv

The easiest way to install and use pip is with virtualenv, since every virtualenv has pip (and it’s dependencies) installed into it automatically.

This does not require root access or modify your system Python installation. For instance:

$ virtualenv my_env
$ . my_env/bin/activate
(my_env)$ pip install SomePackage

When used in this manner, pip will only affect the active virtual environment.

See the virtualenv installation instructions.

Installing Globally

pip can be installed globally in order to manage global packages. Often this requires the installation to be performed as root.


We advise against using easy_install to install pip, because easy_install does not download from PyPI over SSL, so the installation might be insecure. Since pip can then be used to install packages (which execute code on your computer), it is better to go through a trusted path.


pip requires either setuptools or distribute.

See the Distribute Install Instructions or the Setuptools Install Instructions

If installing pip using a linux package manager, these requirements will be installed for you.


If you are using Python 3.X you must use distribute; setuptools doesn’t support Python 3.X.

Using get-pip

After installing the requirements:

$ curl -O
$ [sudo] python

Installing from source

After installing the requirements:

$ curl -O
$ tar xvfz pip-X.X.tar.gz
$ cd pip-X.X
$ [sudo] python install
