안녕하세요 npm install parcel-bundler -D 입력시 아래 사진과같은 오류가 뜨는데 어떻게 해결하면 좋을지 문의드립니다. 감사합니다.

안녕하세요 !  NPM 지역설치와 전역설치가 아직 이해가 안가서요 ㅠ. 예를들어 jquery를 전역으로 설치하면 시스템 레벨에서 사용 가능하다는건데,,, 지역으로 설치해도 로컬에서 작동은 하는데 왜 전역설치가 필요한걸까요...? 시스템레벨에서 사용한다는 말이 이해가 안가요 ㅠㅠㅠ흑흑..

강의 초반의 node.js는 pkg파일 다운받아서 분명히 제대로 설치했습니다. 그 다음에 강의 후반부에 나오는 npm install -g firebase-tools를 터미널에서 입력했는데 전부 에러가 나서....원인도 모르겠고 그래서 혼자 해결이 안 되어서 질문 올립니다. 답변 부탁드립니다.

안녕하세요 아주 맨처음(2강)에 선생님 깃허브에서 파일을 설치 받고 강의에 따라서 터미널을 켜서 npm i 를 하였는데 에러가 뜹니다... 신기하게 cd로 client해서 npm i 를 한거는 다운이 됩니다.  근데 전체 폴더에서 npm i가 되지 않아서 npm run dev를 했을 때 실행조차 되지 않네요 ㅠㅠ  에러를 봤는데 버전 차이인가요..? 사진첨부 합니다. <npm i 에러 사항> <npm run dev 에러 사항>
