Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/blog
Using the URLconf defined in django_introduction.urls, Django tried these URL patterns, in this order:
admin/
blog/
The current path, blog, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
我看到别的同学有这个问题，也没有解决
路劲：Django_introduction/urls.py
urlpatterns = [
path('admin/', admin.site.urls),
path('blog/', include('blog.urls'))
]
