我正在尝试实现 django-freeradius，但是当我在项目的 urls.py 中的 urlspatters 中写入行 * 时，出现错误cannot import name 'ReadOnlyAdmin' 。我曾尝试在https://github.com/openwisp/django-freeradius/blob/master/tests/urls.py中使用相同的配置，但它不起作用。
# 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),
]
我已经安装了： Python 3.6.8 Django 2.2.4 django-filter 2.1.0 django-freeradius 0.1a0 openwisp-utils 0.2.2
这些是我在 settings.py 中的应用
# 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',
]
而且，这是我运行python manage.py runserver ()时的完整错误

如果有人能给我这个错误的原因，我很感激。
