Pip install for both pythons

Question

I\'m new to pip and I\'ve use it to install some module on my system, say pyglet, successfully. I have 2 versions of python, 2.7 and 3. When I use python3, pyglet works fine

Answer 1

pip will only install to one python environment.

It sounds like pip has installed to your python3 environment and you need to install again to python2.

The pip script knows which python it is to installs for by the python in the #! line

To get a pip for your python 2 either there is already a pip2* script on your machine or you will need to install pip for python2

See this question for details about installing pip

Answer 2

I think what you need is virtualenv https://pypi.python.org/pypi/virtualenv . virtualenv is a tool to create isolated Python environments
