Cannot find module greenlet

Question

Trying to install https://github.com/miguelgrinberg/Flask-SocketIO on Google App Engine, module is installed on lib/greenlet.so, but not loaded.

Traceback (most recent call last):

Answer 1

Probably won't work as it uses C extensions not available on GAE.

https://developers.google.com/appengine/docs/python/tools/libraries27

It's the sort of thing there are other tools for (task queues etc) on GAE anyway.
