The same thing now happens when attempting install of rpi_ws281x.
Using the suggested --use-pep517 option also did not work.
Again, some others install fine(e.g. pip install StupidArtnet).
And all of them installed fine on the same Pi a month ago.
Since I'm a beginner here, any insight into understanding, or at least best practices for, pip/wheel/setup.py etc would be appreciated. Especially why python-dev would be required here when it wasn't needed a month ago (some deprecation / new strict checking?). I thought the whole point of PyPi/pip/wheel was that you didn't need to worry about dev and build stuff?
