vagrant up启动失败，提示：
Vagrant is attempting to interface with the UI in a way that requires a TTY
错误信息：

 [D:\vag]$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Clearing any previously set network interfaces...
==> default: Available bridged network interfaces:
1) Intel(R) Centrino(R) Wireless-N 2230
2) Realtek PCIe GBE 绯诲.?у.?
3) VirtualBox Host-Only Ethernet Adapter

==> default: being used to connect to the internet.
Vagrant is attempting to interface with the UI in a way that requires
a TTY. Most actions in Vagrant that require a TTY have configuration
switches to disable this requirement. Please do that or run Vagrant
with TTY

这是因为多网卡Vagrant无法选择使用哪一个，解决办法：
禁用掉另外其他网卡
修改vagrantfile文件，添加桥接网卡
（建议用不含中文的网卡，我用本地网卡“Realtek PCIe GBE 系列控制器”失败，换成无线“Intel(R) Centrino(R) Wireless-N 2230”亲测成功）：
vm.network “public_network”, bridge: “Intel(R) PRO/1000 PL Network Connection”#（引号中的网卡换成你电脑上的网卡）
运行VAGRANT_HOME\bin\vagrant.exe，会提示一个信息让你升级

"Press any key to continue"...

等更新完之后就可以正常启动vagrant up了（据说在OSX中也适用）
