ImportError: cannot import name 'connection' in logs when deploying via App Engine

[jeremykeen]

In which file did you encounter the issue?

python-docs-samples/appengine/flexible/pubsub/main.py

Did you change the file? If so, how?

No

Describe the issue

Error when deploying to App Engine:
from google.cloud.pubsub.connection import Connection File "/env/lib/python3.4/site-packages/google/cloud/pubsub/connection.py", line 19, in <module> from google.cloud import connection as base_connection ImportError: cannot import name 'connection'

In the CLI I eventually get the below error and the app simply is repeatedly relaunching.

ERROR: (gcloud.app.deploy) Error Response: [13] Timed out when starting VMs. It's possible that the application code is unhealthy.

Hi @jkeenest does this work locally? Can you share the entire stacktrace/deploy output?

locally run..

Traceback (most recent call last): File "main.py", line 22, in <module> from google.cloud import pubsub File "C:\Users\keenj\AppData\Local\Programs\Python\Python35-32\lib\site-packages\google\cloud\pubsub\__init__.py", line 27, in <module> from google.cloud.pubsub.client import Client File "C:\Users\keenj\AppData\Local\Programs\Python\Python35-32\lib\site-packages\google\cloud\pubsub\client.py", line 21, in <module> from google.cloud.pubsub.connection import Connection File "C:\Users\keenj\AppData\Local\Programs\Python\Python35-32\lib\site-packages\google\cloud\pubsub\connection.py", line 19, in <module> from google.cloud import connection as base_connection ImportError: cannot import name 'connection'

Hi Jeremy, it seems you might have an old/broken install of the google cloud libraries. Can you send over the output of pip freeze?

You should use a virtualenv when working locally, this will ensure the sample has the correct version of the dependencies.

Tried again with a new clone and virtualenv locally. This worked. Now for deploying in App Engine... I was getting errors from Cloud Compute re: alpha not enabled. I will try to reproduce. Changed zones and now it works.
