After upgrading to 4.8.0, I am not able to generate Library

[zonito]

When I run below command

python lib/endpoints/endpointscfg.py get_client_lib --output ../PGAPIs/PGAndAPI java -bs gradle api_handler.TestApi --hostname=guru.com

I get below error

WARNING:root:Could not find either the Cloud SDK or the App Engine Python SDK.
If you encounter errors, please make sure that the SDK binary path is in your
PATH environment variable or that the ENDPOINTS_GAE_SDK variable points to a
valid SDK root.

Here is my requirements.txt

dateutils==0.6.6
google-api-python-client==1.7.6
google-endpoints==4.8.0
google-endpoints-api-management==1.11.0
inflect==0.2.5
pre-commit==1.3.0
pycrypto==2.6.1
pylint==1.4.1

And when I set ENDPOINTS_GAE_SDK to google cloud SDK - then it uses 4.6.1 version.

After requirements.txt, here are list of installed library

And If it uses 4.6.1 then I get #172 issue.

[inklesspen]

You say "And when I set ENDPOINTS_GAE_SDK to google cloud SDK - then it uses 4.6.1 version."

But the Google Cloud SDK does not include version 4.6.1 of the Endpoints library. How do you know it is using that version?

You must provide a path to the Google Cloud SDK to use the Endpoints tools, because they require the App Engine SDK libraries.
