최근에 컴퓨터 한 대를 새로 조립하여 총결산을 하였다.
brew 설치
1. brew 설치

$ curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1

2, 설치 완료 후 실행

$ brew

프롬프트 Please run brew update!
3. 프롬프트에 따라 업데이트, 실행

$ brew update

오류: Error:/usr/local must be writable!
4./usr/local 디렉터리에 권한을 부여하고 실행

$ sudo chown -R $(whoami) /usr/local

5. 재집행

$ brew update

Homebrew no longer needs to have ownership of /usr/local. If you wish you can

return /usr/local to its default ownership with:

  sudo chown root:wheel /usr/local

6、프롬프트에 따라/usr/local/share/doc/homebrew 삭제, 실행

$ rm -r -f /usr/local/share/doc/homebrew

7. 재집행

$ brew update

설치가 성공했습니다.
2. node 설치

$ brew install node

node 자체 npm, npm가 있으면 아주 happy, make youself happy.
