To uninstall an application that was installed with "pip install" or "pip install -e", run "pip uninstall Zzz".
If you used easy_install or "python setup.py install" or "python setup.py develop" instead of pip, you'll have to uninstall it manually. Chdir to the virtualenv's site-packages directory. Delete any subdirectories and files corresponding to the Python package, its metadata, or its egg link. For our sample application these would be zzz (Python package), Zzz.egg-info (pip egg_info), Zzz.egg (easy_install directory or ZIP file), and Zzz.egg-link (egg link file). Also edit easy-install.pth and delete the application's line if present.
