試したこと

vagrant stausで状態を確認したがちゃんと仮想環境に入れていた。
このエラーは初めてなので試したことはほぼない

ここに問題に対して試したことを記載してください。

補足情報（FW/ツールのバージョンなど）

ここにより詳細な情報を記載してください。

Answer 1

mkdir': Permission denied @ dir_s_mkdir - /home/vagrant/work/CARAVAN (Errno::EACCES)

エラーメッセージの通りです。
あなたにディレクトリを作る権限がありません、という意味です。

1回目はできたのですから、手順を見直してください。
