I have OS Mojave and already have Xcode command line tools installed.
ERROR:

node-gyp rebuild

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

node: v8.9.1, npm: v5.5.1 I also have this problem.
npm install node-gyp@latest -g
It can solve this problem.
