Revert the `--no-site-packages` option with virtualenv
python, virtualenv
Solution
Try removing (or renaming) the file `no-global-site-packages.txt` in your `Lib` folder under your virtual environment.
Where venv is the name of your virtual environment, and python3.4 corresponds to whichever version of python involved, for example:
$ rm venv/lib/python3.4/no-global-site-packages.txt
And if you change your mind and want to put it back:
$ touch venv/lib/python3.4/no-global-site-packages.txt
Note: If you don't see the above file, then you have a newer version of virtualenv. You'll want to follow this answer instead
Problem
I have created a virtualenv using the `--no-site-packages` option and installed lots of libraries. Now I would like to revert the `--no-site-packages` option and use also the global packages. Can I do that without recreating the virtualenv? More precisely: I wonder what exactly happens when creating a virtualenv using the `--no-site-packages` option as opposed to not using that option. If I know what happens then I can figure out how to undo it.
