Local package.json exists, but node_modules missing, did you mean to install?

오늘도 만난 에러메세지

그 중 이 문장이 해결방법일 것같다.

Local package.json exists, but node_modules missing, did you mean to install?

package.json을 이용해서 module을 깔아야하는거 같은데

그걸 어떻게 하는지 모르겠다고..

으우

json이용해서 npm 모듈 깔기를 찾고 공부해봐야겠다

그전에 node.js 기본 활용법과

npm에 대해서 알아봐야겠네
