【问题描述】：

有人可以告诉我如何理解这个 rake 跟踪并指出我解决这个问题的正确方向吗？我尝试执行 rake db:migrate，然后收到一条错误消息“rake aborted！无法加载此类文件 -- ruby/debug/ide'。

我确保已安装 ruby-debug-ide gem，运行 bundle install，并确保我在 rvm 中使用了正确的 ruby 版本。当我运行跟踪时，这就是我得到的：

rake aborted!
cannot load such file -- ruby/debug/ide

请忽略这个问题，我最谦虚的道歉。在 GemFile 中发现问题。另一位开发人员对导致问题的 GemFile 进行了更改。为一个新项目参加 Rails 速成课程 :-)
