我不确定如何调试它。在本地运行这个 ruby​​/sinatra/thin 应用程序我没有任何问题。然而，在 Heroku 上，应用程序似乎没有加载，显示“未找到。”。我不确定如何理解日志：

有任何想法吗？

我克隆了 repo，但无法通过 运行它rackup，这是 Heroku 运行应用程序所依赖的。当直接通过 Ruby 运行 Sinatra 应用程序时，它确实有效。以下是我所做的更改，使其可以使用rackup：

配置.ru

require 'rubygems'
require 'bundler'

Bundler.require

require File.expand_path 'app.rb', File.dirname(__FILE__)
run App

如果你有子类，运行子类，否则使用 Sinatra::Application

我还删除了所有$:.unshifts我发现的东西，因为它们是邪恶的。
