Question

###前提・実現したいこと
macOSX(10.11.4)にて、vagrant+chefで開発環境を構築したいと思っております。

この辺りのサイトを参考に、構築を進めてみたのですが
chef verifyで、エラーが発生してしまい、躓いてしまっております。

$ chef --version
Chef Development Kit Version: 0.12.0
chef-client version: 12.8.1
berks version: 4.3.0
kitchen version: 1.6.0
```こちらのように、chefDKのインストールはうまく行っていると思っております。

###発生している問題・エラーメッセージ
http://bino.hotcom-web.com/wordpress/archives/332
こちらのサイトで言う**chef-zero knife-zeroのインストール**の部分まで完了後
**knifeの初期設定**の部分で下記のエラーが発生してしまっております。

こちらのサイトなどを参考に`chef exec chef verify`にしてみたりもしてのですが、結果は変わりませんでした。
