django - Heroku 上的 Django：ModuleNotFoundError：没有名为“app_name”的模块

Question

我在将我的 Django 应用程序与 django rest 框架一起部署到 heroku 时遇到了一些麻烦。奇怪的是，推送和部署到 Heroku 没有问题，但部署后会崩溃。这是我的文件结构：

我已经在我自己的机器上运行了它，它工作得很好。src.apps.SrcConfig有趣的是，当我使用除in之外的任何其他路径时，我的应用程序无法推送和部署到 Heroku ，INSTALLED_APPS因为它给了我相同的 ModuleNotFoundError。除此之外，我确实获得了成功的部署，但应用程序崩溃了。我什至从 heroku 克隆了我的项目并在本地运行我的项目，没有任何问题。这是来自 heroku logs --tail 的日志：

鉴于此路径在我的本地主机中运行良好，我真的不确定这里有什么问题。我将不胜感激任何帮助。
