Enable global site packages in an existing virtualenv| by jpic | python virtualenv
Nowadays, virtualenv uses --no-site-packages by default. This means that the created virtualenv will not access global site-packages modules ie. /usr/lib/python2.7/site-packages/. To enable global site-packages again, just remove this file:: your_env/lib/python2.7/no-global-site-packages.txt Why would you do that ? Some modules are complicated to install (xpyb) or take too much time to compile (pyqt). Using the distro packages can be pretty useful !
