Abstract:
Calling pip.get_installed_distributions() from a directory with a setup.py file returns a list which does not include the package(s) listed in the setup.py file.

Steps to reproduce:

1. Create a virtual environment and activate it.
2. Download any python git project with a setup.py file to a directory (e.g. git clone https://github.com/behave/behave.git /tmp/behave)
3. Install the project using python setup.py install.
4. Call pip.get_installed_distributions() from the directory which contains the setup.py file.
5. Call pip.get_installed_distributions() from outside the directory which contains the setup.py file.
6. The results from 4 and 5 differs.

I sincerely apologize for it taking more than a year for somebody to say this, but I think this is in the wrong bug tracker and should be reported to the pip project at https://github.com/pypa/pip/issues

Donald, could you confirm?

Yes, Python vendors pip, but is not maintaining it - it should be filed in https://github.com/pypa/pip/issues.
