Google App Engine 'No module named pwd'

Question

I managed to run my Google App Engine project (I use Python Flask to develop a web application), but when I upgraded my system from Ubuntu 12.04 to 14.04. The App Engine project has become immune to the local system, while it works well in a production environment. I am also updating my project by putting my source code on github, so I deleted everything and again cloned a new repository of this from my github account. But when I run the project, it gives me the following error, if anyone has encountered this error, before please help me.

I use this command to run my project

$ dev_appserver.py src/ 

and get this error as output on the terminal

If anyone has resolved this issue, please help me fix the following issue.

Answer 1

google_appengine/google/appengine/tools/devappserver2/python/sandbox.py has a list of _WHITE_LIST_C_MODULES , and adding 'pwd' to it worked for me.

Google actually runs in the sandbox. Since there is no problem in the production environment, the older GAE SDK will support pwd import, but they are going to remove it.

Answer 2

What version of queries are you using?

Can you illustrate the following:

 import requests requests.version 'xxx' $ dpkg -l | grep requests 

On the side of the note: Probably the version of the request that you are using is somehow outdated, I would advise you to upgrade, if possible, to version 2.3.4 or the latest version and try it !.
