ModuleNotFoundError: No module named 'tasklets'

Question

I'm playing with GAE but I realized that when I try to start the .py file I get this error. What can I do? Thanks

  python3 test.py runserver
Traceback (most recent call last):
      File "test.py", line 6, in <module>
        from google.appengine.ext import ndb
      File "/usr/local/lib/python3.6/dist-packages/google/appengine/ext/ndb/__init__.py", line 7, in <module>
        from tasklets import *
    ModuleNotFoundError: No module named 'tasklets'

Answer 1

The NDB library is only available in the standard environment GAE, which only works with python 2.7.

So either switch to the standard environment (and python 2.7) or use the flexible environment instructions for Using Cloud Datastore.
