Conflicting of google packages

[Avinash-Raj]

In which file did you encounter the issue?

https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/appengine/standard/endpoints-frameworks-v2/echo/main.py

Did you change the file? If so, how?

No, I didn't change the source file.

Describe the issue

I have installed the latest version of google cloud sdk, google-cloud-sdk-app-engine-python on my Ubuntu PC as mentioned in the docs in-order to test google-cloud-endpoints-framework sample app.

But on invoking an api request, I got the below traceback. Seems like there is a conflict between google package inside GAE sdk and the google package installed automatically to the lib folder because of google-endpoints framework package.

Here comes the full traceback.

Local development with endpoints framework v2 isn't currently supported, you'll need to deploy the app.

@jonparrott I can't able to generate OpenApi configuration. I don't know why endpoints v2 choose an already existsing package named google .

$ python lib/endpoints/endpointscfg.py get_openapi_spec api.StoryBoxApi --hostname storybox-api.endpoints.storybox-backend.appspot.com
Traceback (most recent call last):
  File "lib/endpoints/endpointscfg.py", line 633, in <module>
    main(sys.argv)
  File "lib/endpoints/endpointscfg.py", line 629, in main
    args.callback(args)
  File "lib/endpoints/endpointscfg.py", line 487, in _GenOpenApiSpecCallback
    application_path=args.application)
  File "lib/endpoints/endpointscfg.py", line 332, in _GenOpenApiSpec
    application_path=application_path)
  File "lib/endpoints/endpointscfg.py", line 183, in GenApiConfig
    module = __import__(module_name, fromlist=base_service_class_name)
  File "/home/gemini/projects/storybox-backend/src/api/__init__.py", line 19, in <module>
    import endpoints
  File "/home/gemini/projects/storybox-backend/src/lib/endpoints/__init__.py", line 29, in <module>
    from apiserving import *
  File "/home/gemini/projects/storybox-backend/src/lib/endpoints/apiserving.py", line 74, in <module>
    from google.api.control import client as control_client
ImportError: No module named control

I wondered why there is a different error than the previous one. So I get into this lib/endpoinst/apiserving.py file and add these two line

import google.api
print google.api.__file__ 

before from google.api.control import client as control_client and after executing the OpenAPI command , I got this output.

/usr/local/lib/python2.7/dist-packages/google/api/__init__.pyc

So there is another google package installed on my pc.

Ok, whatever it is, I should get the same original error if I try to generate OpenAPI config file.

Yep, so I would recommend activating an empty virtualenv before running endpointscfg.py so that your system packages don't cause issues.

[Avinash-Raj]

Now, it works .. Thanks :-)

[Avinash-Raj]

@jonparrott I think local development of endpoints v2 framework was supported now https://cloud.google.com/appengine/docs/standard/python/endpoints/test_deploy . pls let me know how to resolve the original traceback?

[theacodes]

@Avinash-Raj I suggest filing an issue over on https://github.com/cloudendpoints/endpoints-python

@Avinash-Raj: The link you provided refers to endpoints v1...

[Avinash-Raj]

Yep.. later only I realized. Waiting for the working of endpoints V2 locally.

Any progress on making endpoints V2 available locally? Deploying a GAE takes several minutes which really slows down the development cycle if I need to deploy every time I make a change.
