Description
This must be a variant of #38 .
In this case it affects projects with the standard directory structure, where .git and setup.py are in the same directory - but where the package directory is a submodule of another repository.
When building wheels for various projects, I often have the wheel-building machinery in a repository, and the project I am building as a sub-module (e.g. matplotlib-wheels and many others). For pip wheel . in the submodule, the version string is incorrect:
$ mkdir mod # Make an empty superproject
$ cd mod
$ git init
$ # Add some submodule using (latest master) versioneer
$ git submodule add https://github.com/matthew-brett/transforms3d.git
$ # Make wheel with `pip wheel`
$ cd transforms3d/
$ pip wheel .
$ # Version string is incorrect
$ ls *.whl
transforms3d-0+unknown-py2-none-any.whl
It is correct for python setup.py bdist_wheel:
$ python setup.py bdist_wheel
$ ls dist
transforms3d-0.2.1+5.g7631d2a-py2-none-any.whl
See matplotlib/matplotlib#6605 for the original report.
