“安装Docker”时，Meteor.js的Mupx部署失败

Question

我有Ubuntu 14.04，开发它并希望在同一台计算机上安装测试服务器。它在Virtual Box中运行。

所以我按照Github上的所有步骤进行Mupx设置，并观看了Meteor.js指导的视频告诉我观看的视频。当我接到命令时：

mupx setup

它向我显示错误的屏幕：

nejc@nejc-vb:~/Meteor Projects/CSGO/CSGO-deploy$ mupx setup

Meteor Up: Production Quality Meteor Deployments

Configuration file : mup.json
Settings file      : settings.json
