在VScode中使用Docker时出现错误：error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.37/containers/json: 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.
解决方法：
尝试：docker-machine env default
按提示输入：& “C:\Program Files\Docker Toolbox\docker-machine.exe” env default | Invoke-Expression
输入：docker ps 没有报错
问题解决
