Answer 1

假設你的安裝失敗出於同樣的原因作爲我的，你會注意到錯誤日誌的狀態：

"You have to install development tools first." 

因此，安裝xcode並嘗試：

xcode-select --install 

按照屏幕上的說明，您應該是金手指。作爲參考，這是我嘗試時收到的錯誤

Answer 2

如果您安裝了XCODE，則需要打開。 由於操作系統需要添加組件，並且在打開應用程序時添加了這些組件。

再試運行

sudo gem install compass

享受！

得到了同樣的問題，也用xcode-select --install但沒有幫助。 我從這裏https://developer.apple.com/downloads/?name=for%20Xcode
