npm install 관련된거 전부 설치하고 npm run build 쳤더니, 저런 에러가 뜨네요

npm start 눌러서 사이트 확인 결과 부트스트랩 , css도 제대로 작동 하지 않는 것같습니다.

물론 부트스트랩도 설치 했구요!

이유가 무엇일까요...?

store라는 이름의 프로젝트로 이사갈 때 

파일복붙 뿐만 아니라 설치하셨던 라이브러리들도 전부 다시 설치해주셔야합니다 

bootstrap이나 styled component 이런거를 쓰셨다면 설치과정을 다시 밟도록 합시다 

그리고 index.js에 있던 것들도 까먹지않고 잘 복사하셔야할듯요
