Managing Python installations

Question

There are many versions of Python, and it becomes difficult to manage them all.

Often I need to install one module into 3 different versions of Python.

Is there a tool which can simplify things?

I'm on Windows.

Thanks.

Answer 1

Are you using virtualenv? If not, you definitely want to check that out: http://pypi.python.org/pypi/virtualenv

It helps you by managing and switching between several virtual Python environments, with different versions of Python if you want to.

There are loads of tutorials of how to set it up, all over dem interweb.

Answer 2

What Legogris said: use virtualenv.

I just answered a question on pip, virtualenv, and virtualenvwrapper applicable here. I highly recommend this combination of tools for maintaining isolated python environments.

As a further point, I strong recommend using the no-site-packages option so that each virtualenv has all its requirements in one place.
