我正在关注 Rails 网站上的 Rails3 教程第 2 版。但是，我不想使用 rails 服务器，而是想在 OS X Lion 上使用我的 apache 设置。因此，我安装了Passenger 和Passenger Preference Pane。我可以毫无问题地进入欢迎页面，但是如果我单击链接查看我的应用程序环境，我会收到以下错误消息：
Ruby (Rack) application could not be started
These are the possible causes:
There may be a syntax error in the application's code. Please check for such errors and fix them.
A required library may not installed. Please install all libraries that this application requires.
The application may not be properly configured. Please check whether all configuration files are written correctly, fix any incorrect configurations, and restart this application.
A service that the application relies on (such as the database server or the Ferret search engine server) may not have been started. Please start that service.
Further information about the error may have been written to the application's log file. Please check it in order to analyse the problem.
Error message:
Could not find coffee-script-source-1.3.1 in any of the sources (Bundler::GemNotFound)
Exception class:
PhusionPassenger::UnknownError

如果我查看/Library/Ruby/Gems/1.8/任何子目录，我发现没有引用咖啡脚本。但是，快速ash$ bundle show coffee-script-source向我展示了 gem 文件位于/Users/ash/.rvm/gems/ruby-1.9.3-p194@rails3tutorial2ndEd/gems/coffee-script-source-1.3.1
（nb如果我使用rails服务器我没有这个问题，但这不是我想要的解决方案）
作为一个 Ruby 新手，我应该如何配置我的乘客设置以找到正确的文件？
