Django + Apache：[wsgi：error] ModuleNotFoundError：没有名为django_project1'的模块

Question

使用Apache通过Linode启动我的第一个Django应用程序。一切都进行得很好，直到我不得不完成发布。当我尝试访问站点的IP时，出现“ 500 Internal Server Error”（500内部服务器错误）。根据错误日志，我看到有一个wsgi错误。该错误表明没有找到模块“ django_project1”（这是我的项目的名称）。

我已经看到了很多有关此错误的示例，但是似乎没有关于该错误发生原因的全面解释，而且没有一个示例具有相同的解决方案。感谢您提供任何反馈意见。

下面我包括了我的内容：
