Cannot use Google Cloud in GAE app

Question

The following line in the Google App Engine ( webapp.py) application does not allow importing the Google Cloud library :

from google.cloud import storage

With the following error:

ImportError: No module named google.cloud.storage

I did some research and found the following articles helpful:

• https://cloud.google.com/appengine/docs/python/tools/using-libraries-python-27#installing_a_library
• stack overflow
• https://www.simonmweber.com/2013/06/18/python-protobuf-on-app-engine.html

Using a combination of the methods suggested in the above articles, I did the following:

• Create a file requirements.txt:

  google-cloud==0.19.0
  

• Import this library with pip:

  pip install -t lib -r requirements.txt
  

• Use the following code in the file appengine_config.py:

  import os
  import sys
  import google
  libDir = os.path.join(os.path.dirname(__file__), "lib")
  google.__path__.append(os.path.join(libDir, "google"))
  sys.path.insert(0, libDir)
