ImportError: No module named 'django.core.urlresolvers'

I am working on Django project where I need to create a form for inputs. I tried to import reverse from django.core.urlresolvers. I got an error:

line 2, in from django.core.urlresolvers import reverse ImportError: No module named 'django.core.urlresolvers'

I am using Python 3.5.2, Django 2.0 and MySQL.

I had the same error, but that was just because of my url.py file. I fixed it like below:

from drf_spectacular.views import (
SpectacularAPIView,
SpectacularSwaggerView,
)
from django.contrib import admin
from django.urls import path

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/schema/', SpectacularAPIView.as_view(), name='api-schema',),
    path('api/docs/',  SpectacularSwaggerView.as_view(url_name='api-schema'), name='api-docs',),
]

Upgrading Django 1.9 (Python 2.7) to Django 3.2 (Python 3.9)

This could be solved in a one line bash replacement:

grep -ril "from django.core.urlresolvers" your_source_code_folder | xargs sed -i 's@from django.core.urlresolvers@from django.urls@g'

In my case the problem was that I had outdated django-stronghold installed (0.2.9). And even though in the code I had:

from django.urls import reverse

I still encountered the error. After I upgraded the version to django-stronghold==0.4.0 the problem disappeard.

To solve this either you down-grade the Django to any version lesser than 2.0. pip install Django==1.11.29.

For django version greater than 2.0 use:

from django.urls import reverse

in your models.py file.

urlresolver has been removed in the higher version of Django - Please upgrade your django installation. I fixed it using the following command.

pip install django==2.0 --upgrade

If your builds on TravisCI are failing for this particular reason, you can resolve the issue by updating the Django Extensions in your requirements.txt

pip install --upgrade django-extensions

This will update the extensions to use Django 2+ modules.

Django 2.0 removes the django.core.urlresolvers module, which was moved to django.urls in version 1.10. You should change any import to use django.urls instead, like this:

from django.urls import reverse

Note that Django 2.0 removes some features that previously were in django.core.urlresolvers, so you might have to make some more changes before your code works. See the features deprecated in 1.9 for details on those additional changes.

For those who might be trying to create a Travis Build, the default path from which Django is installed from the requirements.txt file points to a repo whose django_extensions module has not been updated. The only workaround, for now, is to install from the master branch using pip. That is where the patch is made. But for now, we'll have to wait.

You can try this in the meantime, it might help

- pip install git+https://github.com/chibisov/drf-extensions.git@master

- pip install git+https://github.com/django-extensions/django-extensions.git@master
