为什么我不能与厨师一起安装一个无所事事的环境？证书验证失败（OpenSSL :: SSL :: SSLError）

我的环境：

OS: Mac 10.10.1
rbenv: rbenv 0.4.0-129-g7e0e85b
Ruby: ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-darwin14.0]

我的Vagrantfile：

# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  # Use Ubuntu 14.04 Trusty Tahr 64-bit as our operating system
  config.vm.box = "precise32"

  # Configurate the virtual machine to use 2GB of RAM
  config.vm.provider :virtualbox do |vb|
    vb.customize ["modifyvm", :id, "--memory", "2048"]
  end

  # Forward the Rails server default port to the host
  config.vm.network :forwarded_port, guest: 3000, host: 3000

  # Use Chef Solo to provision our virtual machine
  config.vm.provision :chef_solo do |chef|
    chef.cookbooks_path = ["cookbooks", "site-cookbooks"]

    chef.add_recipe "apt"
    chef.add_recipe "nodejs"
    chef.add_recipe "ruby_build"
    chef.add_recipe "rbenv::user"
    chef.add_recipe "rbenv::vagrant"
    chef.add_recipe "vim"
    chef.add_recipe "mysql::server"
    chef.add_recipe "mysql::client"

    # Install Ruby 2.1.2 and Bundler
    # Set an empty root password for MySQL to make things simple
    chef.json = {
      rbenv: {
        user_installs: [{
          user: 'vagrant',
          rubies: ["2.1.2"],
          global: "2.1.2",
          gems: {
            "2.1.2" => [
              { name: "bundler" }
            ]
          }
        }]
      },
      mysql: {
        server_root_password: ''
      }
    }
  end
end

我的厨师档案：

site "http://community.opscode.com/api/v1"

cookbook 'apt'
cookbook 'build-essential'
cookbook 'mysql'
cookbook 'ruby_build'
cookbook 'nodejs', git: 'https://github.com/mdxp/nodejs-cookbook'
cookbook 'rbenv', git: 'https://github.com/fnichol/chef-rbenv'
cookbook 'vim'

运行后vagrant up，出现以下错误：

我发现这篇文章：

• http://railsapps.github.io/openssl-certificate-verify-failed.html

我可以确认我的openssl版本：

➜  MY_RAILS_PROJECT  openssl version
OpenSSL 1.0.1j 15 Oct 2014

我不知道是什么原因
