It looks like a library duplication issue. How did you install libraries? How did you install Cloud SDK?
As a preemptive measure, you may consider uninstalling all Google packages from your local machine, then delete the lib folder in your GAE app folder, and re-create it. This being done, you should run: pip install -t lib google-auth google-auth-httplib2 google-api-python-client --upgrade Does this address your problem?
