TL;DR - don't be in such a hurry to upgrade to 3.9. I'll bet the full errors would show pip is calling setup on the sdist version because you've updated to 3.9 and there's no wheel for 3.9 for matplotlib yet. The fallback, compilation, usually fails for Windows users, although you could attempt to follow the project's instructions for getting a build environment set up correctly. When various projects which have binary wheels release their versions supporting a new Python release is up to them; this happens every time a new X in the Python 3.X series is released. You can check for the presence of binary wheels for your system and Python version by querying for the package on pypi.org and clicking to see the downloadable files. There is a place you can get unofficial builds of many popular packages early on, but I kind of don't like to recommend people use "unofficial" builds. With suitable cautions, you can look there if you want (you'd be looking for names containing 'cp39') https://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib -- https://mail.python.org/mailman/listinfo/python-list
