机架/乘客在 Dreamhost 上失败 [英] Rack / Passenger fails on Dreamhost

问题描述

我是 Rails 的新手 &Ruby 并一直在关注 http://ruby.railstutorial.org/ruby-on-rails-tutorial-book 和 amy 尝试将演示应用程序部署到启用了 Dreamhost 乘客的主机上，当我尝试运行该应用程序时失败:

I am new to Rails & Ruby and have been following the http://ruby.railstutorial.org/ruby-on-rails-tutorial-book and amy trying to deploy the demo app to my Dreamhost passenger enabled host and when I try to run the app if fails with:

Ruby (Rack) 应用程序无法启动

以及以下回溯(尽可能格式化):

and the following backtrace (formatting the best I can):

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

我的 environment.rb 文件有:

My environment.rb file has:

# 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机器上运行良好，但一旦我部署它就崩溃.我猜我在配置文件中遗漏了一行，或者从我收集的研究中遗漏了一些与我的宝石有关的东西.

My app runs fine on my local machine but just craters once I deploy it. I am guessing I am missing a line in a config file or something to do with my gems from what I gather researching this.
