我正在尝试在macos中创建迷你dcos集群。
我的minidcos版本是-

$ minidcos --version
    minidcos, version 2019.02.17.1

当我运行下面的命令来创建集群时，我得到一个错误-

$ minidcos vagrant create ./dcos_generate_config.sh --agents 0
    Bringing machine 'dcos-e2e-f2c21a1a-a220-4a33-a528-493a11f16440-master-0' up with 'virtualbox' provider...

我不确定这个错误的根本原因是什么？
