Django manage.py runserver得到了AppRegistryNotReady：模型尚未加载

我用manage.py runserver从命令行运行django时遇到了问题。Django manage.py runserver得到了AppRegistryNotReady：模型尚未加载

几个月前，Django 1.5使用相同的代码。

今天我想再次拾起代码并运行在Django 1.8.3和python2.7.10上。现在

，得到了错误的位置：

任何人都知道如何解决它？

谢谢。

您正在使用哪种夹层版本？ – knbk

夹层是3.1.9，我知道它是旧的，但我之前更改了一些代码，所以我不想从官方使用最新版本。我认为我不应该改变很多代码来修复这个人。我想改变代码先运行，然后尝试转移到正式版本 – Wesley

看来你至少需要4.0.0与Django 1.8一起使用。您需要升级夹层，或将必要的更改回送到本地副本。 – knbk

我认为你需要为你去为不同版本的Django的改变你的wsgi.py文件。

import os 
import sys 

from django.core.handlers.wsgi import WSGIHandler 

os.environ['DJANGO_SETTINGS_MODULE'] = 'YourAppName.settings' 
application = WSGIHandler()

并尝试评论settings.py中导入的所有第三方应用程序。

1/.manage.py runserver将使用您的wsgi.py，但它看起来像您在顶部显示的堆栈跟踪不包括wsgi文件。因此，错误发生在wsgi文件加载之前。

2]这可能是您的Django设置的问题。例如，可以在一个不存在的目录中LOGGING一个文件名。

3]或检查this

它不起作用。其实，目前我使用：从django.core.wsgi导入get_wsgi_application application = get_wsgi_application（），无法正常工作。我不认为它与wsgi.py有关，因为我从mange.py启动应用程序 – Wesley

尝试运行python manage.py检查此命令。 –

得到了同样的错误... – Wesley
