Dealing with multiple Python versions and PIP?


The current recommendation is to use python -m pip, where python is the version of Python you would like to use. This is the recommendation because it works across all versions of Python, and in all forms of virtualenv. For example:

# The system default python:$ python -m pip install fish# A virtualenv's python:$ .env/bin/python -m pip install fish# A specific version of python:$ python-3.6 -m pip install fish

Previous answer, left for posterity:

Since version 0.8, Pip supports pip-{version}. You can use it the same as easy_install-{version}:

$ pip-2.5 install myfoopackage$ pip-2.6 install otherpackage$ pip-2.7 install mybarpackage

EDIT: pip changed its schema to use pipVERSION instead of pip-VERSION in version 1.5. You should use the following if you have pip >= 1.5:

$ pip2.6 install otherpackage$ pip2.7 install mybarpackage

On Windows, you can execute the pip module using a given Python version through the Python launcher, py.exe, if you chose to install it during Python 3 setup.

py -3 -m pip install packagenamepy -2 -m pip install packagename

You can be even more specific and request an exact sub-version of Python:

py -3.6 -m pip install packagename

To get a list of all installed Python versions available through the launcher, run:

py --list

Alternatively, you can launch the desired Python executable directly:

C:/path/to/specific/python.exe -m pip install packagename


/path/to/python2.{5,6} /path/to/pip install PackageName doesn't work?

For this to work on any python version that doesn't have pip already installed you need to download pip and do python*version* setup.py install. For example python3.3 setup.py install. This resolves the import error in the comments. (As suggested by @hbdgaf)
