Python Python API - KeyError: _module

Question

I am trying to use quickstart.py ( https://developers.google.com/gmail/api/quickstart/python ) according to the Google Gmail API using oauth2. I get the following error.

Traceback (most recent call last): File "quickstart.py", line 68, in <module> main() File "quickstart.py", line 54, in main credentials = get_credentials() File "quickstart.py", line 37, in get_credentials credentials = store.get() File "/usr/local/lib/python2.7/dist-packages/oauth2client/client.py", line 407, in get return self.locked_get() File "/usr/local/lib/python2.7/dist-packages/oauth2client/file.py", line 54, in locked_get credentials = client.Credentials.new_from_json(content) File "/usr/local/lib/python2.7/dist-packages/oauth2client/client.py", line 302, in new_from_json module_name = data['_module'] KeyError: '_module' 

Answer 1

Finally, I figured it out. The client_secret.json file downloaded from the Google API console must be placed in the same directory as the python quickstart.py file, and not inside ~/.credentials . This fixes the problem.
