Rails无法在调试中启动

Question

我做了：

gem install ruby-debug

然后安装......

我推出了使用：

rails server -u -p 3002

（我也尝试过-d）

我明白了：

=> Booting WEBrick
=> Rails 3.0.1 application starting in development on http://0.0.0.0:3002
=> Call with -d to detach
=> Ctrl-C to shutdown server
You need to install ruby-debug to run the server in debugging mode. With gems, use 'gem install ruby-debug'
