Heroku发布时Django模块未找到错误

Question

我遇到的问题和之前很多人说的类似，但在我这儿还是没解决。当我把Django项目部署到Heroku上时，出现了一个ModuleNotFoundError的错误，而在本地运行时一切正常。我使用的是Django 4.0和Python 3.10.13。

Heroku的发布日志：

ModuleNotFoundError: No module named 'opportunities.settings.heroku_staging'

目前我的项目结构如下：

在Heroku上，我把DJANGO_SETTINGS_MODULE设置为opportunities.settings.heroku_staging。根据这个项目结构，这应该没问题，但我还是遇到了这个错误。
