`django-admin shell` TypeError crash with ipython installed

[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 prove 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
• Was this Django project working before?

The traceback seems to have been cut but there 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 without removing that app first 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new project and try the commands there so you can detect if the problem is actually caused by Django and not by broken/out of date apps.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.

Thanks!

not sure what it is or how it was involved, but it was traitlets indeed.

Resolved with pip uninstall traitlets

As for your questions:

completely new user, completely new installation via
pip install django

django-admin startproject poll

django-admin runserver --settings=poll.settings works
django-admin runserver doesn't work

this ticket can remain closed

now add scaffold/generators and I'm a happy newbie;)

For what it's worth, I couldn't reproduce the reported crash:

$ PYTHONPATH=. django-admin shell --settings=mysite.settings
