Heroku Procfile 找不到网络进程

Question

I am trying to launch a server on Heroku using Flask and Gunicorn. I have a Procfile which I have both tried creating using echo "web: gunicorn annallAPI:app" > Procfile and with adding the line to a Procfile in vs code. Still everytime I get:

remote: -----> Discovering process types remote: Procfile declares types -> (none)

I have seen problems point to the wrong name, fx if it is ProcFile and another pointing to the incorrect encoding, saying it needs to be UTF-8. I have the correct name and I can't convert to UTF-8 because the original_charset has UTF-8.

The build succeeds and then if I make a request to the server, it of course fails. For the record, I am using an M1 Mac. The error I get in the Heroku log is:

at=error code=H14 desc="No web processes running" method=GET path="/" host=xxx-api.herokuapp.com request_id=65f19b67-87a1-46bf-84f4-20f4ab36e85b fwd="130.208.240.12" dyno= connect= service= status=503 bytes= protocol=https I tried doing heroku ps:scale web=1 to start a web process which I don't think should work if the Procfile doesn't have a set web process. It gave me the error:

Scaling dynos... ! ▸ Couldn't find that process type (web).

1. Make sure that you have created requirements.txt which lists out all libraries including gunicorn

2. Create Procfile - this file basically has no extension and contains web: gunicorn yourwsginame:app Personally, I recommend you create this file manually and edit it using a text editor
