我是新來的紅寶石，並試圖建立我的開發環境（Windows 10）。我安裝了ruby和rails，但無法安裝。從我閱讀的內容開始，我首先需要DevKit。所以我按照這裏的指導安裝它：如何在Windows上安裝ruby的'byebug'？
https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
，然後嘗試安裝寶石，但沒有運氣。 我試圖卸載，然後強制安裝DevKit，但仍不能通過安裝。 這就是我所看到的：
C:\RubySDK>gem install byebug
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing byebug:

是否有其他解決方法呢？ 感謝
