From Oauth2client.service_account Import ServiceAccountCredentials : Cannot Import Name 'opentype'

I use python 3.6.0. I want to play with the Google Drive API. When I import oauth2client.service_account I get this error : Traceback (most recent call last): File 'test.py', li

Solution 1:

Consider upgrading your google-auth module

pip install --upgrade google-auth-oauthlib

and also the pyasn1_module, which is reponsible for implementation of ASN.1 types and codecs as a Python package

pip install --upgrade pyasn1-modules

UPDATE Working solution: Force install your modules

pip install -U -I pyasn1 pyasn1-modules
