Heya guys. I don't know what version of oauth2client did I use, but since 2016-03-15 I got an error
cannot import name 'SignedJwtAssertionCredentials'
using
from oauth2client.client import SignedJwtAssertionCredentials
And the problem is that I can not downgrade my oauth2client to 1.1 or 1.5.2 version
pip install oauth2client==1.5.2
gives me an error:
PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.4/dist-packages/httplib2-0.9.dist-info/DESCRIPTION.rst'
What can i do?
