Vagrant：* 未知的配置部分“disksize”

在我的机器上配置 Vagrant 环境期间，我收到了以下消息：

流浪汉： * 未知的配置部分“disksize”。

它是在插件安装后显示的。

这里是vagrantfile:

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure("2") do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.
  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://atlas.hashicorp.com/search.

  config.vm.box = "bento/ubuntu-16.04"
  config.disksize.size = '150GB'
  config.vm.provider :virtualbox do |vb|
  vb.gui = true
  end

  # Disable automatic box update checking. If you disable this, then
  # boxes will only be checked for updates when the user runs
  # `vagrant box outdated`. This is not recommended.
  # config.vm.box_check_update = false

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.

  config.vm.network "forwarded_port", guest: 8888, host: 8887

  # Create a private network, which allows host-only access to the machine
  # using a specific IP.

  config.vm.network :private_network, ip: "192.168.33.12"
  config.vm.hostname = "dsvm"

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  # config.vm.network "public_network"

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.

  config.vm.synced_folder "./shared_directory", "/shared_directory"

  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
  config.vm.provider "virtualbox" do |vb|
    # Display the VirtualBox GUI when booting the machine
    #vb.gui = true

    # Customize the amount of memory on the VM:
    vb.memory = "4096"#"2048"
    vb.customize ["modifyvm", :id, "--cableconnected1", "on"]

  end

  # View the documentation for the provider you are using for more
  # information on available options.

  # Define a Vagrant Push strategy for pushing to Atlas. Other push strategies
  # such as FTP and Heroku are also available. See the documentation at

  # config.push.define "atlas" do |push|
  #   push.app = "YOUR_ATLAS_USERNAME/YOUR_APPLICATION_NAME"

  # Enable provisioning with a shell script. Additional provisioners such as
  # Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the

我尝试过改变容量disksize.size到更小的尺寸，但没有成功。

可能是什么问题呢？

您需要安装插件：

vagrant plugin install vagrant-disksize
