我试图部署一个应用程序到Heroku，但是当我推我的config.ru文件时，我有错误。
跟随Heroku的日志:

跟随config.ru文件:
require './app'
run Sinatra::Application
我的主文件是app.rb
帮忙吗?
(尝试将此作为注释推送…格式不好)
仅从日志中很难知道。app.rb文件中有什么内容?通常人们会这样做:
require 'rubygems'
require 'sinatra' # or Bundle.require
require 'app/mystuff'
run Sinatra::Application
但是很难知道你是否需要sinatra和其他所有东西从你的'app.rb'文件
登录到heroku，然后将dynos的数量缩放为0。保存，然后扩大规模。在我身上发生过几次，每次都有效。
