mac git clone error:xcrun:error:invalid active developer path(/Library/Developer/CommandLineTools)

背景
升级Mac系统后,在终端使用git clone等相关命令失败,报错

xcrun:error:invalid active developer path(/Library/Developer/CommandLineTools),missing xcrun at:/Library/Developer/CommandLineTools/usr/bin/xcrun

1.问题排查

1.查看git是否已经安装

# 命令
which git

# 结果
/usr/local/bin/git

说明git已经安装

2.查看git帮助信息
git --help
1
报错同上:

xcrun:error:invalid active developer path(/Library/Developer/CommandLineTools),missing xcrun at:/Library/Developer/CommandLineTools/usr/bin/xcrun

综上git已经安装但是git命令不能正常使用,可能是git安装包被损坏了,于是重新安装一下git

3.重新安装git
brew install git
1
安装过程中出现如下错误信息:

Error: The following formula:
git
cannot be installed as a binary package and must be built from source.
Install the Command Line Tools:
xcode-select --install

Error: Git must be installed and in your PATH!
Error: The following formula:
git
cannot be installed as a binary package and must be built from source.
Install the Command Line Tools:
xcode-select --install

根据提示信息可知需要重新安装一下xcode-select;

解法:安装xcode-select
综上分析需要重新安装xcode-select,在终端执行如下命令

xcode-select --install
1
安装完成后在执行一下:

git --help

可以正确输出信息说明git已经恢复正常,可以使用了
