Unable to start App Engine application after updating it via Google Cloud SDK

Recently, I have updated Google App Engine from 1.9.17 to 1.9.18 via Google Cloud SDK by using command 'gcloud components update' in Windows 7 64 bit. After that I wasn't able to start any project using the App Engine launcher. Getting this error:

Traceback (most recent call last):

ImportError: No module named docker
2015-03-05 19:11:27 (Process exited with code 1)

I even installed the latest Google Cloud SDK, but I'm getting the same error.

I'm able to install the appengine SDK 1.9.18(without using Google Cloud SDK) and able to run the project successfully.

This error is happening only for the App Engine launcher installed via Google Cloud SDK in Windows 7.

This issue is raised in App Engine Issue Tracker: Issue 125. I recommend you to star this issue.

Jumping on the answer from @Tzach and adding some info.

The file to modify is containers.py

for me it is located here : C:\Program Files\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine\google\appengine\tools\docker

If you can't modify it because the file is open in an application, it is in fact that the folder is protected. Just copy/paste the file on your desktop and modify it from there. then copy it back in the original folder.

If installing docker-py doesn't work and the stacktrace shows that the error line is:

from docker import docker

Change this line to:

import docker

This is currently an issue with the dev_appserver bundled in the Cloud SDK. A fix will be out soon. In the meanwhile, your options are: 1) Use gcloud preview app run to run your app when using the Cloud SDK 2) Install the standalone AppEngine SDK (which you already mentioned in your question)

This has happened to me today to reinstall the app engine sdk. I could not run my code in the launcher.

I remember reading that is not used pip app engine, but now I have solved the problem.

In short what I did was:

  1. Install pip the footsteps of https://pip.pypa.io/en/latest/installing.html (this also correctly install the setuptools)

  2. Install docker-py by pip: pip install docker-py and ready, I can now run my code in the launcher

P.S. Previously I tried to install the docker-py package, downloaded from https://github.com/docker/docker-py, but lacked setuptools, downloaded and installed the package did not work. So use this with pip.
