Docker：连接时出错

我正在尝试使用RSelenium包时遇到上述错误

shell('docker run -d -p 4445:4444 selenium/standalone-chrome') docker: error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.30/containers/create: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running. See 'docker run --help'. Warning messages: 1: running command 'C:\Windows\system32\cmd.exe /c docker run -d -p 4445:4444 selenium/standalone-chrome' had status 127 2: In shell("docker run -d -p 4445:4444 selenium/standalone-chrome") : 'docker run -d -p 4445:4444 selenium/standalone-chrome' execution failed with error code 127

检查docker环境variables的设置不正确。 请检查下面的命令，

 docker-machine env box 

（注意：默认情况下，docker-machine的env集合是默认的）

否则，您可以将其设置为如下所示

 $ set | grep DOCKER DOCKER_CERT_PATH=C:\Users\mohan\.docker\machine\machines\deis DOCKER_HOST=tcp://192.168.99.100:2376 DOCKER_MACHINE_NAME=deis DOCKER_TLS_VERIFY=1 DOCKER_TOOLBOX_INSTALL_PATH=C:\Program Files\Docker Toolbox $ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS deis * virtualbox Running tcp://192.168.99.100:2376 v17.03.0-ce $ docker ps -a time="2017-03-23T11:11:55-07:00" level=info msg="Unable to use system certificate pool: crypto/x509: system root pool is not available on Windows" CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES $ docker pull busybox time="2017-03-23T11:13:07-07:00" level=info msg="Unable to use system certificate pool: crypto/x509: system root pool is not available on Windows" Using default tag: latest latest: Pulling from library/busybox 7520415ce762: Pull complete Digest: sha256:32f093055929dbc23dec4d03e09dfe971f5973a9ca5cf059cbfb644c206aa83f Status: Downloaded newer image for busybox:latest 

希望这会工作。
