Mac에서 npm 설치시 permission error

맥에 npm을 설치하려고 보니 에러가 떴다

IMac-HNJN:~ HNJN$ npm install -g @vue/cli

'usr/local/... 에서 permission이 거부됐다고 한다. 내 컴퓨터의 이름은 HNJN으로 되어있는데 아마 폴더 이름도 HNJN이지 않을까 usr가 아니라?

 

sudo를 사용해 설정해주고

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

비밀번호를 입력하라고 하면 입력한다.

그리고 다시 설치

npm install -g @vue/cli
