最终通过安装 gem debugger 解决了我的问题相反:http://rubygems.org/gems/debugger

• 将 gem 添加到您的 Gemfile:gem 'debugger', group: [:development, :test]
• 运行 bundler :bundle install

如果您需要有关如何使用 gem 的指导，请观看视频教程 Creating a blog in 15 minutes with Rails - Part 2 .基本上，您需要做两件事来中断服务器呈现页面。

• 添加命令debugger在你的 ruby​​ 代码中的某个地方。如果它是一个 View ，请使用 <% debugger %>相反。
• 使用参数启动服务器:rails server --debugger
