Installing matplotlib via: python3 -m pip install -U matplotlib
fails because kiwisolver cannot be installed. Among a lot of error output is: WARNING: The wheel package is not available.

Not having matplotlib is a MAJOR hurdle for many!


Sstem: Ubuntu 16.04 with Python 3.9rc2 installed from deadsnakes repository (http://ppa.launchpad.net/deadsnakes/ppa/ubuntu/)

This probably isn't an issue with CPython 3.9.0 itself, but rather third-party libraries needing to add 3.9 support and provide wheels, and they may be waiting for 3.9.0 to be officially released (due out today!).

Here's a PR to add Python 3.9 support to Kiwi (aka kiwisolver):

I guess so. Just didn't know how else to bring this to someone's attention, thanks.

But not having matplotlib? Ohmygod!

It still fails. its two weeks after it was first reported. matplotlib is the reason I installed python. I guess I will rollback to older versions one by one to find which one works.
