运行“heroku ps:scale web=1”时出错：“找不到该进程类型（web）。”

Question

I am attempting to deploy a Heroku Dash app from PyCharm. After running the code to deploy it, I got Heroku error code "H14 - No web dynos running," the solution for which is supposed to be heroku ps:scale web=1 . Here is the error I get when attempting to run that line:

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

Others with this problem have been advised to check their procfile. Mine is formatted correctly, with the name "Procfile." Within it is web: gunicorn main:server , where 'main' is the name of the Python file for my app. Any other suggestions about what I could be doing wrong?

Answer 1

The Procfile was created correctly but had not been committed before deployment.
