[오류해결] npm install 설치시 npm ERR! code ERESOLVE

React App 실행 시 node_modules 설치를 위해
npm install 입력했을 때

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

React 버전 문제 때문에 일어나는 문제 인거 같으며

npm install 뒤에 --save --legacy-peer-deps 를 입력하면 된다

npm install --save --legacy-peer-deps
