MAC: solving mojave xcode problem

After upgrade mac software from High Sierra to Mojave, I found some bugs in my terminal.

When I tried to use git command, the error message occurs like below

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

After finding few posts and questions, I found the solution to

xcode-select --install

This will download and/or install xcode tools.

You may need to set path to Xcode by next command

xcode-select --switch /Applications/Xcode.app
xcode-select --switch /Library/Developer/CommandLineTools
