If you get an error message like this one:

It is generally due to a partial uninstallation of python module.

For example if you’ve installed a package myapp that depends on mydeps, then you’ve uninstalled mydeps but you’ve kept myapp, this problem might appear. pkg_resources tries to load mydeps and fails. Solution is easy : reinstall mydeps or uninstall myapp.
