Rails，已安装的Rails调试器

Question

Please see below:

$ 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...

That all looks great, then when I go to fire up the server, it starts up and then exists:

$ 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'

Anyone seen this before?

Thanks

You probably need to put it in the Gemfile, gem 'ruby-debug' and then run bundle install on it. Try that
