我试图安装Laravel Homestead流浪盒。我跟着official documentation，当我运行vagrant up时，我收到此错误：
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'laravel/homestead'...
There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.
