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

Question

After upgrading to Django 4.0, I get the following error when running python manage.py runserver

  ...
  File "/path/to/myproject/myproject/urls.py", line 16, in <module>
    from django.conf.urls import url
ImportError: cannot import name 'url' from 'django.conf.urls' (/path/to/my/venv/lib/python3.9/site-packages/django/conf/urls/__init__.py)

My urls.py is as follows:

from django.conf.urls

from myapp.views import home

urlpatterns = [
    url(r'^$', home, name="home"),
    url(r'^myapp/', include('myapp.urls'),
]

Answer 1

I think a quick fix to this problem is to do followings;

You can easily replace

from django.conf.urls import url

to this:

from django.urls import re_path as url

And keep the rest of code to be same as before. (Thanks @Alasdair)

Answer 2

See in django version 4.0 it will not work. So while installing Django in your Virtual Environment select this version

pip install django==3.2.10

This will definitely solve your error and in main urls.py do this:

from django.conf.urls import url

from django.urls import path,include
