Python Django Rising AppRegistryNotReady在从更新到1.9之后

我读过很多类似的帖子，都有相同的情况，如果有关联的话，我会尝试一些建议。我刚刚更新到Django 1.9，我收到了以下回溯：

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

一个职位提供了以下解决方案：

已安装的应用程序=(
“django.contrib.auth.models.Permission”，

我也按照他们说的那样做了，这将是一个可行的解决方案。还有其他人有这个问题吗？

尝试添加这个（在声明密钥之后）：

---

嗯，它似乎越过了上一个错误，但现在它进入了运行时错误：模型类django.contrib.contenttypes.models.ContentType没有声明显式的应用程序标签，或者不在已安装的应用程序中，或者在加载应用程序之前导入了。再次。我尝试添加了

django.contrib.contenttypes。models.ContentType

到我的

已安装的_应用程序

尝试将'django.contrib.contenttypes'移动到已安装的_应用程序的顶部..没有运气：再次尝试移动已移动的导入django django.setup（）到安装后的\u appsProgress！现在从django.db.models.signals导入post\u syncdb ImportError:无法导入name post\u syncdb

This will no longer be supported in Django 1.9.
