I'm seeing this issue when trying to run pytype over https://github.com/GoogleCloudPlatform/google-auth-library-python

Other libraries it can't seem to find:

• cachetools
• cryptography
• grpc
• pyasn

This issue seems to arise when using pyenv local. Setting the python version using pyenv shell fixes it.

seems to be working with pyenv local now
