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

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

如果您需要有关如何使用 gem 的指导，请观看视频教程使用 Rails 在 15 分钟内创建博客 - 第 2 部分。基本上，您需要做两件事来中断服务器呈现页面。

  • debugger在 ruby​​ 代码中的某处添加命令。如果它是一个视图，请<% debugger %>改用。
  • 使用参数启动服务器：rails server --debugger
