I am working through Chapter 10 and cannot get python manage.py runserver to work when I add “registration” to my INSTALLED_APPS list. If i remove “registration” the runserver command works and I can view my page, but once I add it in, I can’t get localhost to run or anything. Please help?
repo: https://github.com/lizmeister321/hellowebapp
here is what my settings.py looks like:
INSTALLED_APPS = [
‘collection’,
‘django.contrib.admin’,
‘django.contrib.auth’,
‘django.contrib.contenttypes’,
‘django.contrib.sessions’,
‘django.contrib.messages’,
‘django.contrib.staticfiles’,
‘registration’,
]
And here is the error I get when I try and start the server:
Unhandled exception in thread started by <function wrapper at 0x10eaf11b8>
