Railsのインストール

Rubyのバージョンアップ、bundlerのインストールも終わったのでRailsのインストールをします。

インストールするRailsのバージョン決定

参考にしている" パーフェクトRuby on Rails" では、Rubyのバージョン2.1.2とRailsバージョン4.1.1を利用していますがなるべく新しいバージョン使っておいた方が後が楽な気がするので参考書とは別バージョンで開発を進めます。

Ruby gems のページを見ると、最新の安定板が4.2.6、rc版が5.0.0.rc1となっています(2016年5月27日現在)。 バージョン5も気になるところですが、今回は4.2.6をインストールします。
