Anytime i upgrade OSX to newer version, I get the same issue. Here is how i solve it every time:

sudo rm -rf  /Library/Developer/CommandLineTools
xcode-select --install

That's it. Now next time you do npm install or yarn it'll work.

PS: Sometimes you won't be able to install the command line tool through Xcode-select, for example if you are on beta. In that case, you should be able to install it manually from here: https://developer.apple.com/download/more/
