Error) React 초기설정, Mac yarn 설치 에러 npm WARN config global `--global`, `--local` are deprecated.

React 입문 주 차에 앞서 초기 세팅을 하는 과정에서 터미널에 디렉션대로 npm install -g yarn 를 입력했는데 에러 메세지과 다음과 같이 뜬다.

npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.

터미널에서 Brew를 통해서 brew install yarn 명령어를 통해 해결.
