Is there any way to make pip
play well with multiple versions of Python? For example, I want to use pip
to explicitly install things to either my site 2.5 installation or my site 2.6 installation.
For example, with easy_install
, I use easy_install-2.{5,6}
.
And, yes — I know about virtualenv, and no — it's not a solution to this particular problem.
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
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
