Goal: Use GAE with Python and Google Cloud Storage to store and serve an image more efficiently to ultimately use the image API.

Problem: Cannot find correct modules (httplib2 and six) despite successful install.

Run time example

Python Code Sample A:

from google.cloud import storage
from google.appengine.api import app_identity
from google.appengine.ext import blobstore
from google.appengine.ext.webapp import blobstore_handlers
import webapp2

Returns Sample A:

ImportError: No module named google_auth_httplib2

Note: Also had a similar error for six. "no module named six"

Installed Details

python installed at:

C:\Python27

six installed at:

C:\python27\lib\site-packages\six-1.10.0-py2.7.egg

httplib2 installed at:

C:\Python27\Lib\site-packages\httplib2-0.9.2-py2.7.egg-info

Running “C:>pip install httplib2” in the command line returns:

“Requirement already satisfied: httplib2 in c:\python27\lib\site-packages”

Running “C:>pip install six” in the command line returns:

Requirement already satisfied: six in c:\python27\lib\site-packages\six-1.10.0-py2.7.egg

GAE Cloud Storage Client installed at:

C:\Python27\Lib\site-packages\GoogleAppEngineCloudStorageClient-1.9.22.1-py2.7.egg-info

GAE SDK Server Hosting using "dev_appserver.py ." at:

C:\Users\sebastian\Documents\Web Projects\Cookbook

This location also contains the app.yaml file.

Copied modules to app.yaml location

Copied the httplib2 and six-1.10.0-py2.7.egg folders to my app.yaml directory.

Appendix 1:

App.yaml

runtime: python27
api_version: 1
threadsafe: true

handlers:

    - url: /
      script: homegcs.app

    - url: /static
      static_dir: static

    - url: /.*
      script: home.app

    - url: /index\.html
      script: home.app

    - url: /stylesheets
      static_dir: stylesheets

    - url: /(.*\.(gif|png|jpg))$
      static_files: static/\1
      upload: static/.*\.(gif|png|jpg)$

    - url: /admin/.*
      script: admin.app
      login: admin

    - url: /.*
      script: not_found.app

Folder structure containing App.yaml

Your packages either need to be uploaded with the project, or added in app.yaml, if they are available in App Engine. six is an available library, so, in app.yaml, add:

libraries:
- name: six
  version: "1.9.0"

If you put the httplib2 package at the same level as app.yaml, it should upload with the project, and be available in production.

Another user added google_auth_httplib2 as a package as well, and uploaded it with the project. Though I think that should be available directly:

Module google_auth_httplib2 not found after pip installing google-cloud How can I fix it?

** You also have an issue in your url handlers in app.yaml. This is a wildcard for all urls:

- url: /.*
    script: home.app

So, every handler below that will not ever be hit.

  • Thanks, that certainly solves 2 of 4 of the apparent issues. (six and yaml handlers). I've added a picture of the folder structure, as I already have both httplib2 and google_auth_httplib2 in my app.yaml directory but it still throws the same error with regards google_auth_httplib2 not found. – Seb Taylor Feb 08 '17 at 04:26
  • `httplib2` and `google_auth_httplib2` are 2 different packages. Your error is that your code is looking for `google_auth_httplib2`, while you have `httplib2`. Switch your code, or use the correct package (see the link in my answer as to how another user did that) – GAEfan Feb 08 '17 at 05:56

You need to install google-cloud in your project, like this:

pip install google-cloud -t [my_project]/lib/google-cloud

Make sure you create that google-cloud folder first, inside your lib folder. Once you do that, change or create appengine_config.py (in /my_project) and include this:

from google.appengine.ext import vendor

vendor.add('lib/google-cloud')

Everything shoul work now.

  • thanks, tht certainly seems to have fixed some of it. the error now reads "from google.cloud import storage Import Error: No module named cloud" @yamilabugattas – Seb Taylor Feb 22 '17 at 04:43
  • Are you sure the folder is in the directory specified in appengine_config.py? Make sure you pip install in that folder. Also try adding from __future__ import absolute_import at the beginning of the file. – Yamil Abugattas Feb 22 '17 at 11:46
