ModuleNotFoundError: No module named 'google.appengine'

Question

I want to do a google search in python3 on windows. The google instructions say they support python3 and to type "gcloud topic init" for details - but that fails saying no interpreter for python2.7. Do I have to install python2.7 to find out how to get it working on python3?

On python3 I get an error message as below. I have set up an API key and a Custom search engine. I did "pip install google-api-python-client". I downloaded and ran GoogleCloudSDKInstaller. This is the error:

from googleapiclient.discovery import build
service = build("customsearch", "v1", developerKey="xxxxxx")

I get:

[googleapiclient.discovery_cache:WARNING]:file_cache is unavailable when using oauth2client >= 4.0.0 or google-auth (__init__.py:44, time=Apr-07 17:25) Traceback (most recent call last):   File "C:\Users\simon\Anaconda3\lib\site-packages\googleapiclient\discovery_cache\__init__.py", line 36, in autodetect

Answer 1

Needs the parameter cache_discovery=False when creating service, like follows:

service = discovery.build('customsearch', 'v1', credentials=<...>, cache_discovery=False)

Would be great to know why? Just following the quickstart guide results in errors for me – Pyromagnetic

@Rob, I was digging out the same problem and it seems that there is a broken code path in the cache system. You can see in these issues more information, but seems that the cache doesn't works properly with oauth2client > 4.0.0 – Hemicellulose

Answer 2

Although it arrives looking like a cascading error, when looking closely at the first line, this is in fact only a warning:

[googleapiclient.discovery_cache:WARNING]:file_cache is unavailable...

As such, if you don't have access to the instantiation, you can suppress it like this:

import logging

logging.getLogger('googleapiclient.discovery_cache').setLevel(logging.ERROR)

You will still get any actual errors.

Note: the answer I refer to on github has a missing 'n' in 'client'. – Nickey
