为什么我的 vagrant vvv 在 Windows 8 而不是 运行？
Why is my vagrant vvv on Windows 8 not running?
我正确设置了所有内容，甚至能够访问 vvv.dev。但是我晚上用了vagrant halt，早上用了vagrant up，发现开发网站都进不去了。
我可以正常启动虚拟服务器。这是我在执行 vagrant up 时在 cmder 终端中看到的内容的转储。

据我所知（非常有限），每次您停止 Vagrant 时，它都会删除主机文件中的所有条目。简单地说，在 windows Vagrant 需要一个提升的终端，以便它可以编辑主机文件。
如果您没有运行您的终端作为管理员，请先尝试 - 希望有用！
我正确设置了所有内容，甚至能够访问 vvv.dev。但是我晚上用了vagrant halt，早上用了vagrant up，发现开发网站都进不去了。
我可以正常启动虚拟服务器。这是我在执行 vagrant up 时在 cmder 终端中看到的内容的转储。

如果您没有运行您的终端作为管理员，请先尝试 - 希望有用！
