無法構建寶石原生擴展

我不太清楚爲什麼，但我似乎無法安裝任何涉及構建本機擴展的寶石。任何人都可以建議如何開始調試這個問題？這裏的輸出我得到gem install debugger無法構建寶石原生擴展

另外，我最近重新安裝自制軟件，因此這可能是問題？我肯定已經安裝了XCode Developre工具。

這裏的mkmf.log的內容：

你安裝的Xcode命令行工具？他們在你的道路上嗎？ – Doon

他們肯定是安裝的。我將如何檢查他們是否在我的道路上？ – chintanparikh

請注意mkmf.log的內容？（在你的路徑中是gcc？你可以通過運行$ which gcc來檢查） – rogerdpack

這爲我工作：

gem update debugger-ruby_core_source
