No module named pwd

[Vitaliy]

Hi
I'm using django (trunk) with GAE
I got strange exception on appspot (and there were no such exception
on dev_appserver (on windows))

ViewDoesNotExist at /presentations/library/
Could not import <some_my_module>. Error was: No module named pwd

I searched all my files for 'pwd'
and the only place where I found it is
django.contrib.auth.management.commands:

try:
import pwd
except ImportError:
default_username = ''

So this module not found exceptions is definitely not from here
there is no more files in my project that contains word 'pwd'

What is wrong ?

Hi,
 pwd is a Python module (http://docs.python.org/lib/module-pwd.html) that is disabled with Google App Engine.

Please see:
http://code.google.com/appengine/kb/general.html#libraries

Thanks,
Marzia

I also got this error! I understand it is not allowed to import the
pwd module, but WHY is it imported at all?
This is my trace:

while rendering: No module named pwd

I get this error only when visiting one specific view of my
application the first time. If I request it again with exact same
parameters I don't get it.

Any ideas what it could be?

As for me - bug was very stupid...
I had module named 'user'
then I deleted it, but 'import user' were stil inside my code
So it try to import standart python 'user' module and 'pwd' is
importing inside 'user'...

Try to check your code, may be you trying to import 'user' module to..
