Vagrant2.2.6 和VirtualBox6.1.0不兼容問題解決辦法

在安裝完畢vagrant和virtualbox后，

執行命令

vagrant up時出現

No usable default provider could be found for your system.

Vagrant relies on interactions with 3rd party systems, known as
"providers", to provide Vagrant with resources to run development
environments. Examples are VirtualBox, VMware, Hyper-V.

The easiest solution to this message is to install VirtualBox, which
is available for free on all major platforms.

If you believe you already have a provider available, make sure it
is properly installed and configured. You can see more details about
why a particular provider isn't working by forcing usage with
`vagrant up --provider=PROVIDER`, which should give you a more specific
error message for that particular provider.
出現此錯誤提示未安裝virtualbox，但實際已安裝完畢。查資料發現存在版本兼容問題。但目前（今天2020.1.1）均是最新版本，后在github找到答案。

需要修改三處：

1、在/opt/vagrant/embedded/gems/2.2.6/gems/vagrant-2.2.6/plugins/providers/virtualbox/plugin.rb的文件內新增紅色部分

module Driver autoload :Meta, File.expand_path("../driver/meta", __FILE__) autoload :Version_4_0, File.expand_path("../driver/version_4_0", __FILE__) autoload :Version_4_1, File.expand_path("../driver/version_4_1", __FILE__) autoload :Version_4_2, File.expand_path("../driver/version_4_2", __FILE__) autoload :Version_4_3, File.expand_path("../driver/version_4_3", __FILE__) autoload :Version_5_0, File.expand_path("../driver/version_5_0", __FILE__) autoload :Version_5_1, File.expand_path("../driver/version_5_1", __FILE__) autoload :Version_5_2, File.expand_path("../driver/version_5_2", __FILE__) autoload :Version_6_0, File.expand_path("../driver/version_6_0", __FILE__) autoload :Version_6_1, File.expand_path("../driver/version_6_1", __FILE__) end

2、在/opt/vagrant/embedded/gems/2.2.6/gems/vagrant-2.2.6/plugins/providers/virtualbox/driver/meta.rb的文件內新增紅色部分

driver_map   = {
  "4.0" => Version_4_0, "4.1" => Version_4_1, "4.2" => Version_4_2, "4.3" => Version_4_3, "5.0" => Version_5_0, "5.1" => Version_5_1, "5.2" => Version_5_2, "6.0" => Version_6_0, "6.1" => Version_6_1, }

3、在/opt/vagrant/embedded/gems/2.2.6/gems/vagrant-2.2.6/plugins/providers/virtualbox/driver文件夾內新創建version_6_1.rb的文件，並在文件內添加如下信息：

require File.expand_path("../version_6_0", __FILE__)

module VagrantPlugins
  module ProviderVirtualBox
    module Driver
      # Driver for VirtualBox 6.1.x
      class Version_6_1 < Version_6_0
        def initialize(uuid)
          super

          @logger = Log4r::Logger.new("vagrant::provider::virtualbox_6_1")
        end
      end
    end
  end
end

通過一系列修改后，可以正常執行。
