Does pip support extras in extras_require?

See original GitHub issue

It looks like using extras in requirements used in extras_require is not supported. For instance having this in setup.py:

    extras_require={
      'testing': 'Kotti[testing]',
      'development': 'Kotti[development]',
    },

and running pip install -e .[testing] results in Kotti being installed but not any of Kotti’s requirements listed in testing extra. Setuptools’ documentation in section Declaring “Extras” (optional features with their own dependencies) mentions using extras in install_requires but does not mention using it in extras_requires.

I’m using current develop which includes fix from https://github.com/pypa/pip/pull/2785.

Why is this not supported by python setup.py ?

Thank you for taking a look.

It seems that the difference is due to lack of install_requires=['wheel'] in your test (I did not include this as I didn’t think it might be related). After adding it the extras do not get installed.

I suspect the problem could be the same as in issue #3046
