Bug 203961

pywatchman is an officially supported python wrapper that relies on your system's watchman.

https://github.com/facebook/watchman/tree/master/python

I built 4.1.0 from source and watchman + pywatchman works correctly.

Another bug #201031 is a patch to upgrade 3.0.0 to 3.5.0 - however now a few months have passed, and that is out of date now too.
