AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'

Recently I had to reinstall Python due to a corrupt executable. This made one of our Python scripts bomb with the following error:

AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'

The line of code that caused it to bomb was:

from apiclient.discovery import build

I tried pip uninstalling and pip upgrading the google-api-python-client, but I can’t seem to find any information on this particular error.

For what it is worth, I am trying to pull Google Analytics information down via an API call.

Here is an output of the command prompt error:
