Stack 上有几个关于这个错误的问题，但没有答案对我有帮助，奇怪的是，这个错误突然出现了，而之前一切正常。

我所做的是重新启动服务器，突然出现了这样的情况：

为什么在我没有更改任何内容的情况下突然出现此错误，我该如何解决？

每当我打开一个新的 shell 时，我都会运行这个脚本：

export PYTHONPATH=$PYTHONPATH:/Users/cole/Projects/Sites/my_project.com/my_project
export DJANGO_SETTINGS_MODULE=my_project.settings

更新：我稍微草率地编辑了脚本。所需要的只是：

export PYTHONPATH=$PYTHONPATH:/Path/To/Project/Root/Directory
export DJANGO_SETTINGS_MODULE=my_project.settings

转到 manage.py 可用的项目文件夹并运行：

python manage.py 外壳

运行通过错误的 django 语句。（它应该在这里工作）
