TIE- yarn start시 오류 Command failed with exit code 1.

status :

Could not find a production build in the 'C:\Users\user\Front\my-app\.next' directory
디렉토리에 production 을 build 하지 못하는것 같다.

try:

• case 1
  Command failed with exit code 1.
  위코드는 프로젝트 시작시 발생한 에러라고 한다

참조문헌

• solv1
  1) yarn 으로 생성된 node_modules, yarn.lock 삭제

  rm -rf node_modules
  rm -rf yarn.lock

  2) yarn 공유파일 지우고

  yarn cache clean

  3) yarn 재설치

  yarn
  yarn start

• solv2
  1) yarn 업데이트 후 yarn 시작

  yarn update
  yarn start

• solv3
  원인분석 : 코드를 직접 고쳐보자.
  sovl? 아직 분석중 🤷‍♂️
