Heroku 在使用 Procfile 运行 Django 时返回 desc="No web processes running"？

Question

在尝试连接到应用程序时遇到 Django 返回 at=error code=H14 desc="No web processes running" method=GET path="/set-crf/" host=appxxxx.herokuapp.com request_id=8c8ded0a-5470-46c3-b371-29602549d533 fwd="100.38.206.95" dyno= connect= service= status=503 bytes= protocol=https 的问题。添加 Procfile、导入 django-heroku 并设置 requirements.txt 后，似乎没有任何效果。到目前为止，这是我所拥有的：

django_heroku.settings(locals())

我尝试了什么

1. 清空 requirements.txt，部署应用程序，然后冻结以重置 Herokus 缓存。
2. 调整 Procfile，将其重命名为不带大写字母的 procfile。没有效果。
3. 跑heroku ps:scale web=1。 Heroku 仍然显示This app has no process types yet Add a Procfile to your app in order to define its process types.

我不确定还能做什么。我认为问题可能出在我的 Procfile 中，但我完全确定它具有正确的命名约定。我忽略了什么？

对不起，这里的一切都是正确的，我唯一搞砸的是 Procfile 的位置。我不敢相信我花了 3 个小时在这上面
