第一步：进入Homestead所在文件目录

命令：cd

第二步：启动vagrant虚拟机

命令： vagrant up

第三步：更新 Vagrant 盒子

命令：vagrant box update

报错：

localhost:scripts tyrone.zhou$ vagrant box update

==> homestead-7: Checking for updates to 'laravel/homestead'

    homestead-7: Latest installed version: 0

    homestead-7: Version constraints: <= 0.0.0

    homestead-7: Provider: virtualbox

The box 'laravel/homestead' is not a versioned box. The box was added

directly instead of from a box catalog. Vagrant can only

check the versions of boxes that were added from a catalog

such as from the public Vagrant Server.
