【问题讨论】：

嗨阿迪！日志显示未找到模块“my_project”。在您的代码导入或引用“my_project”的某些地方，它没有被安装。检查“my_project”是否是您的应用程序的名称，以及是否在 settings.py 的“INSTALLED_APPS”中列出
嘿马塞洛！感谢回复。我确实注意到了这个错误，但我找不到这个模块在哪里。在创建名为 myproject 的 virtualenv 之前，我正在从事另一个项目。我从那里复制了一些模板代码，但我找不到在这个应用程序中引用相同的地方。我检查了我的 installed_apps，但它不存在。
提示是（在您的 IDE 中，我使用 Visual Studio）您在项目的根目录中搜索“myproject”（不带引号），将显示代码中包含“my_project”的所有文件。也许更容易找到。因为有些地方引用了“myproject”。
@MarcelloBastos 是的，我也是这样做的，发现我的 Proctile 正在引用它。感谢你的帮助。谢谢

【解决方案1】：

所以经过大量研究和阅读 Django 文档、Heroku 文档、StackOverflow 文章后，我发现我一直都做错了，因为我读过类似的文章，人们也有同样的问题。也许这会对你有所帮助：

Procfile 没有扩展名。
您应该通过虚拟环境进行部署
Procfile 脚本很重要，您需要添加web: gunicorn myproject.wsgi，其中myproject 将替换为您的项目名称。
确保 Procfile 在您的根目录中，而不是在项目子文件夹中。

【讨论】：

所以错误是代码中某处对“myproject”的引用。很高兴为您提供帮助，阿迪！
