Question

我是Rails＆amp;的新手Ruby并且一直在关注http://ruby.railstutorial.org/ruby-on-rails-tutorial-book并且我试图将演示应用程序部署到我的Dreamhost乘客启用的主机上，当我尝试运行应用程序时如果失败了：

Ruby (Rack) application could not be started

以及以下回溯（格式化我能做的最好）：

#   File    Line    Location
0   /usr/lib/ruby/gems/1.8/gems/bundler-1.0.7/lib/bundler/setup.rb  10  in `exit'

16  config.ru   1   in `new'
17  config.ru   1

我的environment.rb文件有：

# Load the rails application
<br>require File.expand_path('../application', __FILE__)

# Initialize the rails application
<br>DemoApp::Application.initialize!

我的应用程序在我的本地计算机上运行正常，但是一旦我部署它就会出现陨石坑。我猜我在配置文件中缺少一行或者我从我收集的研究中得到的东西。
