Vagrant正试图以需要TTY的方式与UI进行交互

问题:vagrant up失败,错误如下.我在Windows 7上运行vagrant,基本框是Ubuntu)(files.vagrantup.com/precise32.box).

怎么修好？

    vagrant.bat up

Bringing machine 'default' up with 'virtualbox' provider...
[default] Clearing any previously set forwarded ports...
[default] Clearing any previously set network interfaces...
[default] Available bridged network interfaces:
1) Intel(R) PRO/1000 EB Network Connection with I/O Acceleration
2) Intel(R) PRO/1000 PL Network Connection
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.

Process finished with exit code 1

谢谢
