You need to install ruby-debug to run the server in debugging mode. With gems, use 'gem  install ruby-debug'

退出

这是我第一次尝试使用rails调试器还有任何关于链接的建议，以获得帮助开始使用rails调试器任何新手指南？

Answer 1

确保在Gemfile中包含gem

gem 'ruby-debug' # for ruby 1.8.7+    
gem 'ruby-debug19' # for ruby 1.9.2+

然后运行bundle install

<强>更新

你也可以将它添加到你的Gem文件中，它将处理两个ruby版本。

  gem 'ruby-debug19', :require => 'ruby-debug', :platforms => :mri_19
  gem 'ruby-debug', :platforms => :mri_18

Answer 2

只是跳到乔治所说的，因为Gemfile支持它，你可能想把它放在一个组中，因为你可能不想在生产中使用ruby-debug。

group :development do
  gem 'ruby-debug19' # or ruby-debug for 1.8.7
end

Ruby调试器安装帮助！
