我没有个人资料，但我不知道是否有必要。

当我运行heroku ps:scale web=1我收到一个状态127，但返回相同的错误

Answer 1

错误H14，提示"没有web进程正在运行";基本上意味着你没有运行任何web dynos。您可以使用heroku ps:scale web=1启动一个。

请参考这个问题。

Answer 2

• 我添加了下面的代码

gunicorn appn.wsgi

或

heroku ps:scale web=1 
web: gunicorn appn.wsgi --log-file -

在Procfile仍然面临一个问题:

2022-01-19T15:35:19.020279+00:00 heroku[router]: 
at=error code=H14 desc="No web processes running" method=GET 
path="/" host=****.herokuapp.com request_id=eer2323423er32 fwd="125.16.01.197" 
dyno= connect= service= status=503 bytes= protocol=https

• 我花了一个晚上来解决这个问题，
• 但最后，我在另一个应用程序上部署了相同的代码。这次可以正常工作了:]
