我最近在基于Windows10下，布局laravel+homestead+virtual box
安装的镜像版本是homestead-2.0.0.box文件
在访问站点的时候发现服务器拒绝了我的访问，错误为：502 Bad Gateway
主机与虚拟机之间可以ping通
主要原因可能是：

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.

看了Summer的关于版本冲突的问题，我觉得这是问题之一？
那么怎么找到对应版本的脚本，比如homestead-2.0.0?
