Deprecation issue with upcoming pip 20.2 release

[nabeel-oz]

Installing skater==1.1.2 with pip on Python 3.6.8 generates the following warning. It sounds like this will turn into an issue with the release of pip 20.2.

DEPRECATION: skater==1.1.2 from https://files.pythonhosted.org/packages/5a/99/aa0b52e709a621dfae9fbf8359c9f1ee6d2272e7f53cd2815284e088ec74/skater-1.1.2.tar.gz#sha256=825609b4f354511caf9e1fb315a3b8e288ca4826e896f121e16aeca25c3e4013 did not indicate that it installed an .egg-info directory. Only setup.py projects generating .egg-info directories are supported. pip 20.2 will remove support for this functionality. A possible replacement is for maintainers: updating the setup.py of skater. For users: contact the maintainers of skater to let them know to update their setup.py.. You can find discussion regarding this at https://github.com/pypa/pip/issues/6998.
