Answer 1

My colleague had the same problem. He had an other google package installed, protobuf in his case.

If you try print(google.__path__) , it will probably say something else than the google appengine path. Or try dir(google) to get some idea of what is actually imported.

To solve this, he had to remove protobuf.
