Looks like it might be a problem with Numpy (numpy/numpy#15947), I tried the solutions on that page but didnt seem to help in getting python arcade to install.

Anyone ran into this?

We hardly use numpy, I really need to get it out of there some day.

numpy is also an optional dependecy for shapely. I have not looked into what that means.

This was related to numpy. Recent versions of arcade don't have this problem. We are also removing numpy as a dependency in 2.6
