I have a Debian system currently running with python 2.5.4. I got virtualenv properly installed, everything is working fine. Is there a possibility that I can use a virtuale
Just use the --python (or short -p) option when creating your virtualenv instance to specify the Python executable you want to use, e.g.:
--python
-p
virtualenv --python=/usr/bin/python2.6
N.B. For Python 3.3 or later, refer to The Aelfinn's answer below.
