为什么我在安装 djangocms_vimeo 时收到此错误

Question

我正在尝试安装 djangocms-vimeo 0.4.0。 我通过 pip install djangocms-vimeo 成功安装 但是当我尝试添加 django-project 的设置并在迁移后，我收到此错误：

Traceback (most recent call last):
.......
    class Site(models.Model):
  File "/home/cristian/Anaconda3/lib/python3.8/site-packages/django/db/models/base.py", line 113, in __new__
    raise RuntimeError(
RuntimeError: Model class django.contrib.sites.models.Site doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

这是我的settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'filmapp.apps.FilmappConfig',
    'djangocms_vimeo',
]
