pkg_resources.DistributionNotFound: The 'tinycss2<2,>=0.5' distribution was not found and is required by qstylizer
$ port installed | grep tinycss
py39-tinycss @0.4_0 (active)
Solved by installing py-tinycss2.
looking at the last line of the backtrace it is missing that dependency in qstylizer; I’ll take a look ince I am behind a computer.
