python - Heroku 新手 - "No such type as web"

Question

我正在尝试在 Heroku 上使用 Python/Flask 部署我的第一个应用程序。我真的不知道自己在做什么，只是按照 https://devcenter.heroku.com/articles/python#prerequisites 上的教程进行操作.当我键入命令 heroku ps:scale web=1 时，我收到错误消息“No such type as web”。我的 Procfile 说 web: python scrabble_cheater.py，我相信这是正确的。这是我的终端的日志:

(venv)jason-olsens-macbook-pro:scrabble paulnichols$ heroku status

非常感谢任何帮助!

Procfile 被错误地保存为 .txt 扩展名——一旦我删除了扩展名，它就起作用了。
