Question

I’d usually prefer to create virtualenvs with --no-site-packages option for more isolation, and also because default python global packages includes quite a lot of packages, and usually most of them are not needed.
However I’d still want to keep a few select packages in global, like PIL or psycopg2. Is there a good way to include them into the virtualenv, that can also be automated easily?

If you’re using virtualenvwrapper and you might be able to use the postmkvirtualenv script to automatically create symlinks in the new virtualenv sitepackages directory.

#!/bin/sh
cdsitepackages
ln -s /path/to/system/site-packages/package-name
cdvirtualenv
