將我的Macbook空氣升級到優勝美地後，我一直無法安裝滑軌。有一連串的錯誤，其中一些我已經能夠解決。當前的錯誤，這是我一直在努力的失敗日內解決，看起來像這樣優勝美地滑軌/ Nokogiri安裝錯誤

我運行OSX 10.10.2和ruby -v給我
ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]
注：這似乎是一個重複的，但我相信這不是我一直在研究解決方案，建議對SO和其他地方的天，發佈解決方案s沒有解決錯誤。 Xcode的安裝，與開發工具，所以xcode-select --install給我
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
很多感謝您的幫助！
聖鉬，這似乎已經解決了這一問題 - 太感謝你了！在運行該命令並安裝nokogiri後，Rails成功安裝。 – rainbowsorbet 2015-03-30 22:01:31
