URLpatterns for Django 2 is quite different it can't accept regular expressions any help

WARNINGS: ?: (2_0.W001) Your URL pattern '(<pk>\d+)/$' [name='course_detail'] has a route that contains '(?P<', begins with a '^', or ends with a '$'. This was likely an oversight when migrating to django.urls.path().

According to the What's New in Django 2.0 docs, you can use re_path in place of url to use the legacy regular expression format, or covert to the new path format

    path('<int:pk>/', name='course-detail'),

Though your code seems to be missing the view argument that should follow the URL expression. See path documentation.

Post back if you have more questions. Good luck!!

Here's what I did to get my code to work correctly using Django v. 2.0.3

From the learning_sites/courses/urls.py

from django.urls import path

from . import views


urlpatterns = [
    path('', views.course_list),
    path('<int:pk>/', views.course_detail),
]
