Возникли ошибки при использовании Chef-solo+vagran+AWS+ Mac OS X

Я намеревался использовать Vagrant, Chef-solo для создания среды AWS. Но у меня есть некоторые ошибки, которые я не могу решить. Кто-нибудь может помочь мне?

Шаги, которые я использовал:

1. Установите все необходимое окружение на Mac OS X: например, vagrant, плагин vagrant, виртуальную коробку, шеф-повар, плагин шеф-повара и так далее.

2. Загрузите бродячие файлы конфигурации:

   git clone https://github.com/ICTatRTI/ict-chef-repo
   

3. Vagrantfile

   # vi: set ft=ruby :
   Vagrant.configure("2") do |config|
     # All Vagrant configuration is done here. The most common configuration
     # options are documented and commented below. For a complete reference,
     # please see the online documentation at vagrantup.com.
     #config.vm.box_url = "https://opscode-vm.s3.amazonaws.com/vagrant/opscode_ubuntu-12.04_chef-11.2.0.box"
     #config.vm.box = "opscode-ubuntu-1204"
     config.vm.box = "dummy"
     config.vm.network :forwarded_port, guest: 80, host: 8888
     config.vm.network :forwarded_port, guest: 3306, host: 3333
     config.ssh.username = "ubuntu"
   
     config.vm.provider :aws do |aws, override|
     #config.vm.provider :aws do |aws|
       aws.access_key_id     = 'XXXXXXXXXXXXXXXQ'
       aws.secret_access_key = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
       aws.keypair_name = "usr-aws-2013"
       aws.availability_zone = "us-west-2c"
       aws.instance_type = "t1.micro"
       aws.region = "us-west-2"
       aws.ami = "ami-0849a03f"
       aws.security_groups = ['quicklaunch-1']
       aws.tags = { 
         'Name' => 'tong',
         'Description' => 'vagrant test'
       } 
       override.ssh.private_key_path = "~/.ssh/usr-aws-2013.pem"
       override.ssh.username = "ubuntu"
     end
     config.vm.provision :chef_solo do |chef|
   
        chef.node_name = 'base' 
        chef.cookbooks_path = "./cookbooks"
        chef.roles_path = "./roles"
        chef.add_role "base"
        chef.add_role "ushahidi"
      end
   
   end
   

4. Бежать:

   vagrant up --provider=aws
   

5. Получил следующие ошибки
