python - docker.errors.DockerException : Error while fetching server API version

Question

我想安装此模块，但尝试步骤 docker-compose build ... 时出现问题
我多次尝试更新 Docker 版本并重新启动 Docker。但它没有用。

git clone https://github.com/uhh-lt/158.git
cd 158
docker-compose build

File "/home/ming/.local/bin/docker-compose", line 8, in <module>
    sys.exit(main())
  File "/home/ming/.local/lib/python3.8/site-packages/compose/cli/main.py", line 67, in main
    command()
  File "/home/ming/.local/lib/python3.8/site-packages/compose/cli/main.py", line 123, in perform_command
    project = project_from_options('.', options)
  File "/home/ming/.local/lib/python3.8/site-packages/compose/cli/command.py", line 60, in project_from_options
    return get_project(
  File "/home/ming/.local/lib/python3.8/site-packages/compose/cli/command.py", line 131, in get_project
    client = get_client(
  File "/home/ming/.local/lib/python3.8/site-packages/compose/cli/docker_client.py", line 41, in get_client
    client = docker_client(
  File "/home/ming/.local/lib/python3.8/site-packages/compose/cli/docker_client.py", line 170, in docker_client
    client = APIClient(**kwargs)
  File "/home/ming/.local/lib/python3.8/site-packages/docker/api/client.py", line 188, in __init__
    self._version = self._retrieve_server_version()
  File "/home/ming/.local/lib/python3.8/site-packages/docker/api/client.py", line 212, in _retrieve_server_version
    raise DockerException(
docker.errors.DockerException: Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))

Answer 1

您确定 docker 正在您的系统上运行吗？当 compose 无法通过 docker 套接字连接到 docker 时，您可能会收到该错误(如果未定义任何其他连接方式)。
如果你在linux上运行，通常你可以运行systemctl status docker检查 docker daemon 是否正在运行和 systemctl start docker开始它。
知道什么操作系统和 docker version 会有所帮助。你正在用吗。
