我有django 1.9
我用这个instructions安装了allauth。但是我在运行迁移后遇到以下错误：
./manage.py migrate
错误：
...
RuntimeError: Model class allauth.account.models.EmailAddress doesn't declare an explicit app_label and either isn't in an application in INSTALLED_APPS or else was imported before its application was loaded.
请帮我解决这个问题。
