Python virtualenv

When creating a virtual environment without site packages, do I need to install mysql and the mysqldb adapter, which is in my global site packages, in order to use them in my virtual project environment?

You can also (on UNIX) create symbolic packages with symbolic links from Python site packages to your virtual package sites.

Yes. You will need to install it exclusively for this virtualenv.

See: http://virtualenv.openplans.org/#the-no-site-packages-option

If you create --no-site-packages ENV with virtualenv, it does not inherit any packages from the global site package directory.

If you see files inside the site-packages directory, packages are created using symbolic links.

That way, you can definitely add packages manually by creating these symbolic links for a specific package.

Adam Vandenberg answered this correctly.
