　　DEPRECATION WARNING                            
  Node.js 6.x LTS Boron is no longer actively supported!
  You will not receive security or critical stability updates for this version.
  You should migrate to a supported version of Node.js as soon as possible.
  Use the installation script that corresponds to the version of Node.js you
  wish to install. e.g.  
   https://deb.nodesource.com/setup_10.x — Node.js v10 LTS "Dubnium" (recommended)  
   https://deb.nodesource.com/setup_12.x — Node.js v12 LTS "Erbium"
  Please see https://github.com/nodejs/Release for details about which
  version may be appropriate for you.
  The NodeSource Node.js distributions repository contains
  information both about supported versions of Node.js and supported Linux
  distributions. To learn more about usage, see the repository:
    https://github.com/nodesource/distributions

rbenvとruby-buildのインストール

rbenvはrubyのバージョンを管理するパッケージで，ruby-buildはそのプラグイン．

$ git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
$ source .bash_profile
$ git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
$ rbenv rehash
