Module fails to load on Python 3.12

[tiltowait]

I get the following error trying to import mongomock-motor in Python 3.12. I have run python3.12 -m ensurepip --upgrade, which is a commonly suggested fix for this issue with pkgutil.

Traceback (most recent call last):
  File "<string>", line 1, in <module>

                    ^^^^^^^^^^^^^^^^^^^
AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?

I'm using mongomock-motor 0.0.30, poetry 1.8.3, and Python 3.12.3.

Looks like an issue with mongomock that can be fixed in https://github.com/mongomock/mongomock/issues/889. While this version is unavailable, did you try to install setuptools? It seems to help:

mongomock_motor/$ python3 -V
Python 3.12.4
mongomock_motor/$ python3 -m venv .venv
mongomock_motor/$ source .venv/bin/activate
mongomock_motor/$ python3 -m pip install -r requirements.txt setuptools
...
mongomock_motor/$ make test
... 32 passed ...
