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.
pip v1.4 works with CPython versions 2.6, 2.7, 3.1, 3.2, 3.3 and also pypy.
pip works on Unix/Linux, OS X, and Windows.
Python 2.5 was supported through v1.3.1, and Python 2.4 was supported through v1.1.
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.
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.
pip requires setuptools.
As of pip 1.4, pip recommends setuptools >=0.8, not distribute (a fork of setuptools) and the wheel support requires setuptools >=0.8. setuptools and distribute are now merged back together as “setuptools”.
For details on installing setuptools from scratch, see the install instructions on the setuptools pypi page
pip install --upgrade setuptools
If you had distribute before, this will upgrade to you distribute-0.7.X, which is just a wrapper, that depends on setuptools. The end result will be that you have distribute-0.7.X (which does nothing) and the latest setuptools installed.
