How are you trying to install? Pip? Conda? Which versions?

[OriolAbril]

Hi, just checking in. I am unable to help having only the information you provided. If I had to guess I'd say it is probably due to an old setuptools version, but I am far from an expert on python packaging.

[yurivict]

I am building using Python buildtools within of the FreeBSD ports framework.

It runs python setup.py config, then python setup.py build, ...

[OriolAbril]

I might have found a way to fix the issue. Can you try #26 and see if it builds with your tooling? If so I'll make a new release to fix the issues you are having.

It might also be worth looking into different ways to build the packages though. I hope this works, but relying on setup.py might not work anymore in the future, even with setuptools, see this section or this footnote.

[yurivict]

#26 totally fixed it.

[OriolAbril]

Perfect! Just merged the PR, I'll try to make a new release in a few days
