Macで複数バージョンのRubyを使用するための環境を構築する方法

• 自分の環境はHomebrewを導入しているので、今回はHomebrewを通してrbenvを入れます。

rbenv

インストール

$ brew install rbenv ruby-build

• 確認

   $ rbenv --version
   rbenv 1.0.0
  

   $ brew info rbenv
   rbenv: stable 1.0.0 (bottled), HEAD
   Ruby version manager
   https://github.com/rbenv/rbenv#readme
   /usr/local/Cellar/rbenv/1.0.0 (36 files, 61.9K) *
     Poured from bottle on 2016-05-30 at 09:01:46
   From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/rbenv.rb
   ==> Dependencies
   Recommended: ruby-build ✔
   ==> Options
   --without-ruby-build
   	Build without ruby-build support
   --HEAD
   	Install HEAD version
   ==> Caveats
   Rbenv stores data under ~/.rbenv by default. If you absolutely need to
   store everything under Homebrew's prefix, include this in your profile:
     export RBENV_ROOT=/usr/local/var/rbenv
   
   To enable shims and autocompletion, run this and follow the instructions:
     rbenv init
  

   $ brew info rbenv
