我该如何解决这个问题？
谢谢你的帮助。
上次遇到这个问题是因为找不到需求。从本地更新您的 requirements.txt 文件。
另外你想做的是在你的 settings.py
DEBUG = False
DEBUG_PROPAGATE_EXCEPTIONS = True
为生产添加这些生产线。这会将错误传播到日志中。在那里你可以看到为什么你会收到应用程序错误。
（我敢打赌它丢失了一些包裹。让我知道它是什么。）
您的应用没有任何进程运行。
您需要使用 heroku ps:scale web=1 命令缩放您的 web dyno。
当然，这假设您已经在 Procfile 中配置了 web 进程类型。
今天我遇到了同样的错误。在我的根目录中，我有没有任何扩展名的 Procfile，但是当我在 visual studio 代码中打开代码时，Procfile 的扩展名为 .txt 并且显示为“Procfile.txt”。我刚刚从文件中删除了 .txt 并保存了它。这解决了我的错误。
你可以参考我的post了解更多：

您需要使用 heroku ps:scale web=1 命令缩放您的 web dyno。
当然，这假设您已经在 Procfile 中配置了 web 进程类型。
今天我遇到了同样的错误。在我的根目录中，我有没有任何扩展名的 Procfile，但是当我在 visual studio 代码中打开代码时，Procfile 的扩展名为 .txt 并且显示为“Procfile.txt”。我刚刚从文件中删除了 .txt 并保存了它。这解决了我的错误。
