How can I solve this problem? Many where we recommend that you sudo easy_install pip the team, but it did not help.

Are you sure that the name of the widget class is correct?
I was checking django-redactor and django-redactoreditor and they don't have a class named "JQueryEditor".

Django manage.py runserver got AppRegistryNotReady: Models aren't loaded yet

I hit a problem when run django from command line with manage.py runserver.
The same code is fine with Django 1.5 several months ago.
Today I wanna pickup the code again and run upon Django 1.8.3 and python2.7.10 .
Now, got error here:

I think you need to change your wsgi.py file as you go for different version of Django.
import os
import sys
from django.core.handlers.wsgi import WSGIHandler
os.environ['DJANGO_SETTINGS_MODULE'] = 'YourAppName.settings'
application = WSGIHandler()
And try to comment all third party application imported in settings.py.
1] ./manage.py runserver will use your wsgi.py however it looks like the stack trace you've shown at the top does not include the wsgi file. Therefore the error is occurring before the wsgi file is loaded.
2] This could well be an issue with your Django settings. For example,may in LOGGING a filename in a non-existent directory.
3] or check this

Django/PostgreSQL - ImproperlyConfigured Error

I started a Django project using PostgreSQL and it was working fine after setup, I could add things to the database, view it in admin etc. Being new to Postgres, I thought it would be a good idea to quit the terminal to see if if it would 'auto connect' to the database upon restarting (like SQLite does). However now it throws this error:

When importing the psycopg2 there is no error and inside the psql shell if I type \c it says I have connected to server 'Kyle' (my server name as specified in my django settings) as User 'Kyle' (also as specified in settings).
NB: Using all the latest releases for everything

I think this is a dependency issue, because I realised I wasn't in my virtual environment (it works when I'm in it).

asdas#asdas-ubuntu:~/scratch$
Any idea what could be going on? I've setup everything until this point.

"dgin" is an undefined variable in the sentry configuration
It's likely this is a mistype or something similar, but that's what the error means.
