我是 ruby 新手，正在尝试设置我的开发环境（Windows 10）。我已经安装了ruby和rails，但无法安装byebug。据我了解，我首先需要 DevKit。所以我按照这里的指南安装了它：
https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
然后尝试安装 gem 但没有成功。
我尝试卸载然后强制安装 DevKit 但仍然无法安装 byebug。
这就是我所看到的：
C:\RubySDK>gem install byebug
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing byebug:
