wheels prevent extras_require installs from working

[kmike]

This issue is similar to #1885, so I copy-pasted its title :)

In Python 3.4 and 2.7 virtual environments pip install formasaurus[with-deps] only installs packages from install_requires, not from extras_require['with-deps'].

pip install --no-use-wheel formasaurus[with-deps] tries to install all packages.

The example from #1885 works for me (pip install ipython[test] installs nose).

setup.py file: https://github.com/TeamHG-Memex/Formasaurus/blob/70aa88a50dbc3edf702e31b763ca944ba0995d13/setup.py

I'm using pip 7.1.0.

so pip is detecting the extra properly. Not sure why its not evaluating them correctly.

@kmike what version(s) of setuptools are you using?

[kmike]

@sigmavirus24 setuptools 18.0.1 installed with virtualenv.

Additional case when extras_require do not work as expected is pip install git+https://github.com/TeamHG-Memex/Formasaurus.git@72dc572#egg=Formasaurus[with-deps].

In both cases the problem seems to be with handling of - in with-deps: it seems to be replaced with _ somewhere. Installation of the annotation feature from the same package works fine in both cases.

I wonder if it is related to pypa/setuptools#732.

Do you still have the issue with pip 9.0.1?

[lopuhin]

I think the issue is resolved: both pip install git+https://github.com/TeamHG-Memex/Formasaurus.git@72dc572#egg=Formasaurus[with-deps] and pip install formasaurus[with-deps]==0.7.1 now install requirements from with-deps.

Great :)
