Ошибка импорта "openwisp_utils.admin import ReadOnlyAdmin"

Question

Я пытаюсь реализовать django-freeradius, но я получаю сообщение об ошибке не могу импортировать имя "ReadOnlyAdmin", когда я пишу строку * в urlspatters в urls.py моего проекта. Я пытался использовать ту же конфигурацию в https://github.com/openwisp/django-freeradius/blob/master/tests/urls.py, но она не работает.

# myproject/urls.py
from django.contrib import admin
from django.urls import path, include
from openwisp_utils.admin_theme.admin import admin, openwisp_admin

openwisp_admin()
admin.autodiscover()

urlpatterns = [
    url(r'^', include('django_freeradius.urls', namespace='freeradius')), #* This line
    path('admin/', admin.site.urls),
]

Я установил: Python 3.6.8 Django 2.2.4 django-filter 2.1.0 django-freeradius 0.1a0 openwisp-utils 0.2.2

Это мои приложения в settings.py

# myproject/settings.py
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django_freeradius',
    'django_filters',
]

И это полная ошибка, когда я запускаю python manage.py runserver ()

Я ценю, если кто-то может дать мне причину этой ошибки.

Попробуйте установить разрабатываемую версию openwisp-utils:

pip install --upgrade http://github.com/openwisp/openwisp-utils/tarball/master
