求大佬给指点一下

基于 Laravel 开发博客应用系列-设置 Windows 本地开发环境，碰到了问题求大佬给指点一下
我照着https://laravelacademy.org/post/2124.html这个来搞的，求大神给指点一下。
我用vagrant box add laravel/homestead 这个实在是太卡了，下载不动，我就去https://atlas.hashicorp.com/laravel/boxes/homestead/versions/3.0.0/providers/virtualbox.box下载了一个box。3.0.0是vagrant box add laravel/homestead的时候显示的一个，我就用它了。
下载下来之后 我就百度了一个json运行了一下
{ "name": "laravel/homestead", "versions": [ { "version": "3.0.0", "providers": [ { "name": "virtualbox", "url": "E:/build/laravel/virtualbox.box" } ] } ] }

box list显示有这个。
接下来我就vagrant init laravel/homestead
然后他提示
A Vagrantfile has been placed in this directory. You are now
ready to vagrant up your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
vagrantup.com for more information on using Vagrant.
我接下来运行了
E:buildlaravel>vagrant up laravel/homestead，
却提示
The machine with the name 'laravel/homestead' was not found configured for
this Vagrant environment.
求大神给指点一下该咋整
