我使用流浪汉创建Vagrantfile：
vagrant init somedir/thebox-1.0.0 http://XX.XX.XXX.XXX.XXXX/somedir/thebox-1.0.0.box
我无家可归：
vagrant up
显示（以及其他信息）

work as intended.
In most cases it is OK that the "Window System drivers" installation failed.

现在，如果我通过以下方式销毁VM：
vagrant destroy -f
然后通过以下方式再次将其打开：
vagrant up
仍然报告不匹配项
[default] GuestAdditions versions on your host (6.1.8) and guest (6.0.2) do not match.
该文件已在本地存在：

如何避免出现错误
[default] GuestAdditions versions on your host (6.1.8) and guest (6.0.2) do not match.
何时首次调用vagrant up？
我见过类似How to upgrade to VirtualBox Guest Additions on VM box?的答案。当首次调用vagrant up时，安装vagrant-vbguest不会防止错误。
您会收到此消息，因为已经使用VirtualBox的早期版本（6.0.2）创建了无用的信息框，并且已为此版本在包装盒上]安装了GuestAdditions。但是，现在您运行的是更新版本的VBox（6.1.8），因此系统需要在包装盒上复制更新的工具。
[每次在此框上旋转新VM并在主机上升级VirtualBox时，都会收到此消息。
如果您真的想避免该错误，则需要升级您的包装盒并在包装盒中安装Guest Addition并重新包装包装盒
