导轨，安装Rails调试

Question

请参阅以下内容：

$ sudo gem install ruby-debug 
Successfully installed ruby-debug-0.10.4 
1 gem installed 
Installing ri documentation for ruby-debug-0.10.4... 
Installing RDoc documentation for ruby-debug-0.10.4... 

这一切都看起来不错，然后当我去启动服务器，它启动，然后存在：

$ rails server --debugger 
=> Booting WEBrick 
=> Rails 3.0.3 application starting in development on http://0.0.0.0:3000 
=> Call with -d to detach 
=> Ctrl-C to shutdown server 
Silencing Postgres 
You need to install ruby-debug to run the server in debugging mode. With gems, use 'gem install ruby-debug' 
Exiting 

任何人看到这之前？

感谢

你可能需要把它放在Gemfile中，gem 'ruby-debug'，然后在其上运行bundle install。试试
