在过去的 6 个小时里，我一直在解决诸如修改 $PATH、安装 Gems 等问题，以最终得到应有的一切。但是在我使用它的组件创建项目文件夹并尝试运行服务器之后，我收到了这条消息：-
\KAMAL$ ls
Gemfile README.rdoc app config.ru doc log script tmp
Gemfile.lock Rakefile config db lib public test vendor
\KAMAL$ rails server
=> Booting WEBrick
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
