@YolandaTang from the error message I think you're missing a comma between the apps django.contrib.sites and registration. You can see an example here: https://github.com/macropin/django-registration/blob/master/test_app/settings.py#L14

[joshblum]

@YolandaTang what version of Django are you running?

[VioletLover]

@joshblum it's 2.0.dev20170318191452

[joshblum]

This library doesn't support Django 2.0 yet, the module isn't found since it was removed in Django 2.0 https://docs.djangoproject.com/en/1.11/ref/urlresolvers/#module-django.urls

[VioletLover]

@joshblum Well, thank you!

[VioletLover]

just open the registration folder and find auth_urls.py file and alter the line 'from django.core.urlresolvers import reverse_lazy' to 'from django.urls import reverse_lazy' and add 'on_delete=models.CASCADE' to the '('registrationprofile_ptr', models.OneToOneField(parent_link=True, auto_created=True, primary_key=True, serialize=False, to='registration.RegistrationProfile'))' line in the 0004_supervisedregistrationprofile.py file located in registration/migrations would work for 2.0 dev version of Django.
