ImportError: No module named moves in importing google.cloud.datastore

[vinitpayal]

Exception getting generated on import google.cloud.datastore

Versions :-

• OS : mac(10.13.3) & ubuntu(16.04) [tried on both]
• Python : 2.7.14
• six : 1.9.0 & 1.11.0(tried on both)
• google-cloud-datastore : 1.6.0
• virtualenv : 15.1.0

Stacktrace :

from google.cloud.datastore import helpers
File "/opt/tribes-backend/denv/local/lib/python2.7/site-packages/google/cloud/datastore/helpers.py", line 27, in
from google.cloud._helpers import _datetime_to_pb_timestamp
File "/opt/tribes-backend/denv/local/lib/python2.7/site-packages/google/cloud/_helpers.py", line 30, in
from six.moves import http_client
ImportError: No module named moves

What I tried :-

Tried printing dir(six) after importing in google/cloud/_helpers.py line number 30 in output of which I was able to find moves package inside six and even if I am importing http_client in my virtual environment using from six.moves import http_client it's getting imported correctly but it's just not getting imported inside google/cloud/_helpers.py file.

I have already added six in libraries in appengine_config.py as suggested in documentation at https://cloud.google.com/appengine/docs/standard/python/tools/built-in-libraries-27.

This issue is getting generated only after latest update in google-cloud-sdk-app-engine-python-extras earlier it was working fine.

@jonparrott ISTM that this must be a GAE issue -- if so, please close.

Yep.

@vinitpayal unfortunately these libraries are not yet supported on GAE standard. Please follow this bug for updates: #1893

[vinitpayal]

@jonparrott If I have understood correct you are saying we can't use datastore in GAE standard because I am not including six it's being used by datastore. And that's the origin of exception.

Am I understanding something wrong here ?

@vinitpayal it's more than just that, there are several things we need to do to make these libraries work on standard. Please keep an eye on #1893 for more updates.
