android studio - bug - git - Xcode Command Line Tools

昨天下午更新了下mac系统到版本10.11.3（15D21）后
打开android studio的时候出现了一个bug - 配置的git 出问题了

问题描述：
打开android studio的配置

确认Path to Git executable 无误，点击Test按钮，
提示如下信息：
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

在网上经常漫长查找，解决方案如下：

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重新安装了一遍，重新点击Test按钮，提示成功！
