Node.jsとnpmのインストール

手元の Mac に Node.js と npm がインストールされていなかったのでインストールした手順

homebrew を使って nodebrew をインストール

$ brew install nodebrew
==> Downloading https://github.com/hokaccha/nodebrew/archive/v0.9.2.tar.gz
==> Downloading from https://codeload.github.com/hokaccha/nodebrew/tar.gz/v0.9.2

==> /usr/local/Cellar/nodebrew/0.9.2/bin/nodebrew setup_dirs
==> Caveats
Add path:
  export PATH=$HOME/.nodebrew/current/bin:$PATH

To use Homebrew's directories rather than ~/.nodebrew add to your profile:
  export NODEBREW_ROOT=/usr/local/var/nodebrew

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

zsh completion has been installed to:
  /usr/local/share/zsh/site-functions
==> Summary

インストールできる Node.js のバージョンを確認

$ nodebrew ls-remote

バージョンを指定してインストール (binary を指定したほうがインストールにかかる時間が短いようだ)

$ nodebrew install-binary v6.11.3

自分でインストール先のディレクトリを作らないとダメらしい

$ mkdir -p ~/.nodebrew/src
