Re: [Pydev-users] Setting up Eclipse pydev django development environment

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

What do you mean by running python --version in the Eclipse Terminal? Which
terminal are you talking about?

If you just do a simple script with:

import sys
print(sys.version_info)

and run it by pressing 'F9' inside Eclipse/PyDev what do you get?

Cheers,

Fabio
