Django: dependencies reference nonexistent parent node

ImportError : cannot import 'url' from 'django.conf.urls' after upgrading to Django 4.0

문제

error when running python manage.py runserver

원인

django.conf.urls.url() was deprecated in Django 3.0, and is removed in Django 4.0+.

해결

replace url() with re_path(). re_path uses regexes like url, so you only have to update the import and replace url with re_path.
