Ruby on rails Ruby调试器安装帮助！

我安装了ruby debugger，但即使在此之后，当我尝试使用“-debugger”选项启动rails服务器时，我收到一个控制台错误，表示未安装ruby debugger。请参阅以下日志：-

:~/work_space/rails_apps/Bidding_sys_remaining$ sudo gem install ruby-debug    <<<<<<<

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

：~/work\u space/rails\u apps/Bidding\u sys\u剩余$sudo gem安装ruby debug确保在gem文件中包含gem

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

然后运行bundle安装

更新：

您还可以将它添加到您的Gemfile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

请继续George所说的，由于Gemfile支持它，您可能希望将它放在一个组中，因为您可能不希望ruby debug出现在生产环境中

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

哈，我还以为我能用ruby 1.9进行调试呢。非常感谢。
