npm을 망쳤어?

사내에서 공부회가 있고 node.js를 사용한 개발이므로 npm을 사용했는데 공부회의 HandsOn대로 해도 움직이지 않는다.

$ npm install
npm ERR! code E401
npm ERR! Unable to authenticate, need: Basic realm="GitHub Package Registry"

GitHub Packages를 사용하고 있으므로, GITHUB_TOKEN(퍼스널 토큰)을 아래와 같이 써 있었습니다만, 이것이 이용되고 있지 않은 것 같습니다・・・

$ echo "//npm.pkg.github.com/:_authToken=${GITHUB_TOKEN}" > ~/.npmrc

음. 모르겠어. 환경을 다시 넣는가?

$ brew install npm
Warning: node 14.12.0 is already installed and up-to-date
To reinstall 14.12.0, run `brew reinstall node`

fromula에 npm
그건 그렇고

$ which npm
/usr/local/bin/npm

homebrew로 넣은 것 같지 않아・・・.
그래, 일단 삭제해.

$ sudo rm -rf /usr/local/bin/npm

터미널을 다시 열어

$ npm -v
-bash: npm: command not found

그래서 homebrew로 node를 재설치하면 어떻게 되겠지 ...

readline is keg-only, which means it was not symlinked into /usr/local,
because macOS provides BSD libedit.

For compilers to find readline you may need to set:
  export LDFLAGS="-L/usr/local/opt/readline/lib"
  export CPPFLAGS="-I/usr/local/opt/readline/include"

For pkg-config to find readline you may need to set:

==> Caveats
sqlite is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have sqlite first in your PATH run:
  echo 'export PATH="/usr/local/opt/sqlite/bin:$PATH"' >> /Users/$USER/.bash_profile

For compilers to find sqlite you may need to set:
  export LDFLAGS="-L/usr/local/opt/sqlite/lib"
  export CPPFLAGS="-I/usr/local/opt/sqlite/include"

For pkg-config to find sqlite you may need to set:
