在 Heroku 上部署 Sinatra 应用程序时遇到问题

Question

我是 Ruby 和 Heroku 世界的新手，我正在尝试在 heroku 上部署一个非常基本的 Sinatra 应用程序。我有以下文件：

config.ru：

require './hi'
run Sinatra::Application

hi.rb:

require 'rubygems'
require 'sinatra'

get '/' do
  "Hello from Sinatra on Heroku!"
end

.宝石

sinatra

当推送到 heroku 并启动应用程序时，它会崩溃并在日志中显示以下条目：

问题是 sinatra - 他们更新了它，所以现在一切都在 1.2.6 上顺利运行。
