Docker-machine无法连接到Docker守护进程。 docker守护程序是否在这个主机上运行？

我在Mac OS X上使用Docker 10.10.5我的主要权限有各种各样的问题。 我能够创buildsudo docker-machine create --driver virtualbox test然后结果sudo docker-machine env test

 export DOCKER_TLS_VERIFY="1" export DOCKER_HOST="tcp://192.168.99.102:2376" export DOCKER_CERT_PATH="/Users/michaelaubry/.docker/machine/machines/test" export DOCKER_MACHINE_NAME="test" # Run this command to configure your shell: # eval $(docker-machine env test) 

然后我运行eval $(docker-machine env test) ，结果是open /Users/michaelaubry/.docker/machine/machines/test/config.json: permission denied

我运行sudo chown michaelaubry:staff /Users/michaelaubry/.docker/machine/machines/test/config.json ，仍然open /Users/michaelaubry/.docker/machine/machines/test/config.json: permission denied

然后我尝试这个

 ~ » sudo chown michaelaubry:staff /Users/michaelaubry/.docker/machine/machines/test/ ~ » sudo chown michaelaubry:staff /Users/michaelaubry/.docker/machine/machines/ ~ » sudo chown michaelaubry:staff /Users/michaelaubry/.docker/machine/ ~ » sudo chown michaelaubry:staff /Users/michaelaubry/.docker/ ~ » eval $(docker-machine env test) Error checking TLS connection: machine does not exist 

任何想法我做错了什么？
