我正在按照命令行中的Data Science安装教程,其中包括以下步骤:
$ mkdir MyDataScienceToolbox
$ cd MyDataScienceToolbox
$ vagrant init data-science-toolbox/data-science-at-the-command-line
$ vagrant up
这完全适用于我的一台计算机而不是另一台计算机.为什么？
两台计算机都使用Virtualbox版本:4.3.12和Windows 7.
这是错误消息:
$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Importing base box 'data-science-toolbox/data-science-at-the-command-line'...
There was an error while executing `VBoxManage`, a CLI used by Vagrant
用于控制VirtualBox.命令和stderr如下所示.
