Mac OSX に LAMP スタックと Chef を使用して新しいバージョンの Vagrant をインストールしようとしています。Chef-dk、vagrant、および仮想ボックスがインストールされています。私は、precision32 ボックス (vagrant box add precision32 http://files.vagrantup.com/precise32.box ) と berkshelf (gem install berkshelf および vagrant plugin install vagrant-berkshelf) をインストールしました。すべてを削除して再インストールしようとしましたが、次のエラーが発生し続けます。
