我是第一次使用 Ruby on Rails，试图在 RHEL 6 上设置它。因为包管理器有非常旧的 Ruby 版本。我使用 Ruby 1.9.3 从源代码编译并使用
$gem install rails
使用创建了一个新应用程序
$rails new /path/to/newapp
但是现在当我尝试跑步时
$rails server
它与给定的日志崩溃
=> Booting WEBrick
=> Rails 3.2.1 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting

我试图搜索此错误，但没有找到有效的解决方案。
除此之外，我想指出一些有用的资源，它解释了 Ruby on Rails 的最佳实践。
