我将djangae与一些第三方应用程序一起使用，例如all-auth，django-invitations和django rest框架。当我点击python manage.py migration时，出现以下错误。
AttributeError: type object 'ContentType' has no attribute 'objects'
下面是完整的跟踪

我已安装的应用程序：
INSTALLED_APPS = [
'djangae',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'djangae.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'djangae.contrib.security',
'django.contrib.sites',
'allauth',
'allauth.account',
'allauth.socialaccount',
'allauth.socialaccount.providers.google',
'invitations',
]
有人帮忙吗？
