社内で勉強会があり、node.jsを使った開発なので、npmを使ったのですが、勉強会のHandsOnの通りやっても動かない。
$ npm install
npm ERR! code E401
npm ERR! Unable to authenticate, need: Basic realm="GitHub Package Registry"
GitHub Packagesを使っているので、GITHUB_TOKEN（パーソナルトークン）を下記のように書いていたのですが、これが利用されていないようです・・・
$ echo "//npm.pkg.github.com/:_authToken=${GITHUB_TOKEN}" > ~/.npmrc
むーん。わからん。環境を入れ直すか。
$ brew install npm
Warning: node 14.12.0 is already installed and up-to-date
To reinstall 14.12.0, run `brew reinstall node`
fromulaにnpmって指定したのにnodeはすでに入ってるよって言われた・・・。
ちなみに
$ which npm
/usr/local/bin/npm
homebrewで入れたんじゃなさそうだな・・・。
ええい、一旦削除しちゃえ。
$ sudo rm -rf /usr/local/bin/npm
ターミナルを開きなおして
$ npm -v
-bash: npm: command not found
で、homebrewでnodeを再インストールすればなんとかなるだろ・・・

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"
