运行厨房清单时无法识别Vagrant-winrm

Question

我有一个非常简单的serverspec测试，我正在尝试为平台windows-2012r2运行。当我运行kitchen list时，我得到以下内容：

exception: "#<Kitchen::UserError: WinRM Transport requires the vagrant-winrm Vagra
  plugin to properly communicate with this Vagrant VM. Please install this plugin
  with: `vagrant plugin install vagrant-winrm' and try again.>"
message: 'WinRM Transport requires the vagrant-winrm Vagrant plugin to properly
  communicate with this Vagrant VM. Please install this plugin with: `vagrant
  plugin install vagrant-winrm'' and try again.'

然而，当我运行vagrant plugin list时，我得到以下内容：

vagrant-scp (0.5.7)
vagrant-share (1.1.5, system)
vagrant-winrm (0.7.0)

为什么厨房没有认识到winrm？
