installation difficulties of brozzler[easy] on cygwin and Linux

[beaudet]

I've spent the last couple of days trying to get Brozzler[easy] to work in cygwin and Linux with no success. Brozzler 1.5.18 installs, but Brozzler[easy] does not. due to various dependency conflicts. I've tried with python 3.8 on a fresh ubuntu 20 image and python versions 3.8, 3.7, and 3.5 under cygwin with similar results. I've also tried older versions of Brozzler, e.g. 1.4 which also seem to have dependency issues. It would be great to have a recipe / detailed documentation for getting Brozzler to work on these platforms as I'd really like to test it.

Any advice?
