How to uninstall editable packages with pip (installed with -e)
At {virtualenv}/lib/python2.7/site-packages/ (if not using virtualenv then {system_dir}/lib/python2.7/dist-packages/)
- remove the egg file (e.g.
distribute-0.6.34-py2.7.egg) if there is any - from file
easy-install.pth, remove the corresponding line (it should be a path to the source directory or of an egg file).
An easier way to do the same with the new version of setup_tools is to run the following:
python setup.py develop -u
Which basically does the same as what @glarrain describes in his answer.
