Heroku：未找到并退出进程答案

【问题标题】：Heroku: Not Found & Process ExitedHeroku：未找到并退出进程
【发布时间】：2013-03-10 07:30:39
【问题描述】：

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：

有什么想法吗？

【问题讨论】：

这一行似乎是问题的开始：“2013-03-20T22:38:01+00:00 app[web.1]: bash: bundle: command not found”。您能否发布您的 Gemfile 以及您如何在应用程序中调用 Bundler 来设置要求？哦，还有一些版本的东西——Sinatra、Ruby、Bundler。
嘿@iain，rails 3.2.12，bundler 1.1.5。我在这里开始使用这个项目：github.com/jasonmelgoza/armor
app.rb 顶部的这一行是干什么用的？ $:.unshift File.expand_path('../../../lib', __FILE__) 我没有看到 lib 目录！
呃，我不确定它到底是做什么的我检查了我的文件结构，现在有一个 v 文件夹，在 @iain 之前肯定不存在。它包含像 admin/app/config/lib/log/public/script/test 这样的文件夹。我还下载了一个新的盔甲安装并部署到 Heroku，基本上给了我同样的“未找到”错误。
@iain 忘了那个 v 目录，我不知道它是如何到达那里的，但它肯定没有任何业务。

【解决方案1】：

我克隆了 repo，但无法通过 rackup 让它工作，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。以下是我为使其与 rackup 一起使用所做的更改：

config.ru

require 'rubygems'
require 'bundler'

Bundler.require

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

If you've subclassed, run the subclass, otherwise use Sinatra::Application

我还删除了所有我发现的$:.unshifts，因为它们是邪恶的。
