its only happening on python 3.12 I think. I just got pip installation is working on 3.11. Perhaps theres some way to preempt with a nicer warning message?

Note that 2.17.1 is from October. All subsequent versions explicitly require Python <3.12. I don't see any way to fix this unless we somehow modify all previous packages on PyPI to add this constraint, but that would alter the checksums.

I think the best way forward is:

1. Keep trying to get 3.12 running (#488)
2. In order to prevent similar problems in the future, add hard upper pins to everything and always test them before relaxing.

We release frequently enough that I believe 2. is viable.

I opened #590 to track version bounds.
