次の例外を与えましたこのinclude_granted_scopes引数をサポートしています：http://oauth2client.readthedocs.org/en/latest/source/oauth2client.client.html#oauth2client.client.flow_from_clientsecrets

You は古くなったコード/ドキュメントを使用していますが、他の人は前に同じ問題を報告しています。たとえば、https://groups.google.com/forum/#!topic/google-api-python-client/zQttW4WMUrgです。まだサポートされていない議論がまだthat referenced docにあるのがわかります。

答えを調べているうちに私が得たように、議論は段階的な承認に使用されたようです。 That outdated referenced docは、実際にはIncremental authorizationのセクションを持っています。

To avoid this complexity, you can include previously granted scopes in your authorization requests. For example:

flow = client.flow_from_clientsecrets(...) 
flow.params['include_granted_scopes'] = True
