The problem is that anything that explicitly depends on pyqt5 (as in
'pyqt5' being listed in install_requires) yields a DistributionNotFound
error. I am having this very issue with the recent release of spyder.

A solution is to remove the explicit dependency in order to trick the
setuptools metadata, but it is pretty ugly. Is there really no other
way?
