使用特定版本的Python设置python virtualenv

Question

I am trying to get started with Google App Engine. I have python 2.6 installed in my virtual environment which I wanted to use. But Google App Engine supports python2.5. So I want to set up another python virtual environment with python 2.5.

Can you help me how to do exactly that?

Answer 1

Virtualenv lets you specify a python binary to use instead of the default. On your machine, python probably maps to /usr/bin/python , which will be a symlink to /usr/bin/python2.6 . If you've got Python 2.5 installed, it will be /usr/bin/python2.5

You can create a virtualenv called envname with virtualenv -p /usr/bin/python2.5 envname

Answer 2

Do you specifically need a virtual environment?

Why not just Install Python 2.5 along side your existing 2.6 and just use 2.5 for your GAE development.
