Beginning with Cartopy 0.21, Python 3.8 or above is required.
You are using Python 3.7.15.

This may be due to an out of date pip.

Make sure you have pip >= 9.0.1.

Seems like for python 37, it should either be pinned to a previous version, or just removed.

The py37 subport has been removed with commit 54d400e

So this is fixed.
