python - Django AppRegistryNotReady 错误

Question

将我的项目从 1.8.5 迁移到 1.9b1 会导致下一次回溯

Traceback (most recent call last):
  File "/Users/.../manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)

    raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

Process finished with exit code 1

我的manage.py很简单:

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings.base")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

我检查了 Django 1.9 更新指南，但它没有提供有关应用程序加载的任何信息。

当找不到设置文件时，我通常会看到类似的错误消息堆栈。因此，在这种情况下，您的 settings\base.py 文件要么无法找到，要么缺少 django 1.9 所需的一些设置。

由于这是一次迁移，我假设您正在使用 virtualenv，并且已将 django 1.9b1 pip 安装到新环境中并在那里运行应用程序。

如果是这种情况，请尝试创建一个新的“虚拟”项目来查看干净的 django 1.9 设置文件是什么样子。
