バージョンの切り替えが上手くいかなかった原因
~/.bash_profileに以下を追記する必要があった。
eval "$(rbenv init -)"
これをしないと、rbenvでインストールしたrubyのPATHが反映されない。
$ vi ~/.bash_profile # eval "$(rbenv init -)"を追記 $ source ~/.bash_profile # .bash_profileを読み込み、追記した設定を反映 # 改めてバージョンを確認 $ ruby -v ruby 2.2.5p319 (2016-04-26 revision 54774) [x86_64-darwin14]
