Heroku的新手 - "没有像网络这样的类型"

Question

我正在尝试在Heroku上使用Python/Flask部署我的第一个应用程序.我真的不知道我在做什么,只是按照https://devcenter.heroku.com/articles/python#prerequisites上的教程.当我输入命令时,heroku ps:scale web=1我收到错误消息" No such type as web".我Procfile说web: python scrabble_cheater.py,我认为是正确的.这是我的终端的日志:

Procfile 被错误地以 .txt 扩展名保存——一旦我删除了扩展名，它就可以工作了。
