Vagrant 启动时报错

The provider 'virtualbox' that was requested to back the machine
'homestead-7' is reporting that it isn't usable on this system. The
reason is shown below:

Vagrant has detected that you have a version of VirtualBox installed
that is not supported by this version of Vagrant. Please install one of
the supported versions listed below to use Vagrant:

4.0, 4.1, 4.2, 4.3, 5.0, 5.1, 5.2, 6.0

A Vagrant update may also be available that adds support for the version
you specified. Please check www.vagrantup.com/downloads.html to download
the latest version.

我的vagrant版本是2.2.6
virtualbox版本号是6.1

vargrant不支持当前vbox版本

解决方案

重装一个低版本的virtualbox
或者修改vargrant的配置

这里重点介绍第二个方案：

修改

sudo vim /opt/vagrant/embedded/gems/2.2.6/gems/vagrant-2.2.6/plugins/providers/virtualbox/plugin.rb

添加一行如下图

修改meta.rb

sudo vim /opt/vagrant/embedded/gems/2.2.6/gems/vagrant-2.2.6/plugins/providers/virtualbox/driver/meta.rb

这是vagrant在mac上的默认安装路径，window自己找一下

添加一行"6.1" => Version_6_1

同时在/opt/vagrant/embedded/gems/2.2.6/gems/vagrant-2.2.6/plugins/providers/virtualbox/driver/目录下新建version_6_1.rb文件，文件内容如下：

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
