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

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.
