按照官方文档进行安装 vagrant，一直卡在 vagrant up；
操作系统： whidows 7

我的操作：

vagrant box add firstBox ./virtualbox.box  ==> box: Box file was not detected as metadata. Adding it directly... ==> box: Adding box "firstBox" (v0) for provider:     box: Unpacking necessary files from: file://C:/Users/liumeng/vagrant_get ting_started/virtualbox.box     box: Progress: 100% (Rate: 687M/s, Estimated time remaining: --:--:--) ==> box: Successfully added box "firstBox" (v0) for "virtualbox"!  vagrant init fistBox  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.  vagrant box list  $ vagrant box list firstBox (virtualbox, 0)  vagrant up  // 一直不动，没有任何提示

大家有遇到这个问题吗？
