昨天下午更新了下mac系統到版本10.11.3（15D21）后
打開Android studio的時候出現了一個bug - 配置的git 出問題了

問題描述：
打開android studio的配置

確認Path to Git executable 無誤，點擊Test按鈕，
提示如下信息：
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

在網上經常漫長查找，解決方案如下：

參考：
change xcrun developer path for Android Studio
最佳答案的描述：
I ran into the same problem, however with svn. I found that by installing El Capitan, Xcode was “uninstalled”. I reinstalled Xcode from the App Store and then reinstalled Xcode Command Line Tools via Terminal with

xcode-select –install

After installation, my /Library/Developer/CommandLineTools/usr/bin directory reappeared and svn started working again.

我把xcode重新安裝了一遍，重新點擊Test按鈕，提示成功！

至此，文章結束，希望此文能幫助到你，如果對此文有不同見解，歡迎直接評論！
