Please make `django-admin shell` easier to use.

[pannous]

Please make manage.py shell work out of the box:

> django-admin shell 
django.core.exceptions.ImproperlyConfigured: Requested setting USE_I18N, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. 

> manage.py shell
django.core.exceptions.ImproperlyConfigured: Requested setting USE_I18N ...

After 20 minutes I found the 'solution' to the this problem, but the second issue is unresolved:

django-admin shell --settings=poll.settings
TypeError: catch_config_error() missing 1 required positional argument

full log:

django-admin shell --settings=poll.settings

Please provide more details on what steps you've performed before reaching this point. like:

• How have you installed Django
• Have you installed it in such a way that django-admin.py got copied to /usr/local/bin or is it a remnant from another installation?
• Des your Django project already have some apps added to INSTALLED_APPS or is it a recently created one?
• Was this Django project working before?

The traceback seems to have been cut but there are traces of a 'traitlets' Django application. Is it an app of yours or a third party one? Can you try the manage.py commands you posted but after removing that app from the Django project? Or maybe create a new project and try the commands there so you can detect if the problem is actually caused by Django and not by broken/out of date apps.

Please reopen if you can provide such information.
