If you recently updated to macOS High Sierra and tried to run git commands you would face this error:


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


You can do the following to solve this problem:


xcode-select --install 


This will basically install/reinstall the xcode developer tools and your problem will be solved.
