ImportError: cannot import name 'collections_abc'

Tests are currently failing because of some library version issues:

Looks like we have an old version, and other people have solved this by upgrading (googleapis/google-cloud-python#9965).

ERROR: google-api-core 1.22.4 has requirement six>=1.13.0, but you'll have six 1.11.0 which is incompatible.
ERROR: google-api-python-client 1.12.3 has requirement six<2dev,>=1.13.0, but you'll have six 1.11.0 which is incompatible.

A fresh install doesn't seem to have these issues, and while there are a lot of dependencies on six, I don't see anything conflicting in the pipdeptree output:
