docker机无法启动主机
我最近在我的电脑上安装了Docker工具箱（OS X），虽然我已经在我的其他笔记本电脑上正常工作了，但在这个工具上似乎不能正常工作。 使用docker工具箱安装后，通过docker命令行工具启动（按照docker文档）。 我得到一个主机是不是由于某种原因运行错误？
Machine default already exists in VirtualBox. Starting machine default... exit status 1 Started machines may have new IP addresses. You may need to re-run the docker-machine env command.

Please start this with docker-machine start default 尝试docker机启动默认也无法启动主机：
bash-3.2$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM default virtualbox Stopped bash-3.2$ docker-machine start default exit status 1 Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command. bash-3.2$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM default virtualbox Stopped
这似乎是与Virtual Box 5.0兼容的问题。 尝试在这个Github问题中提到的解决scheme。 Docker没有正确安装
