docker.errors.DockerException:获取服务器API版本时出错

Question

我想安装这个模块，但是当我尝试步骤docker-compose build ...时出现了问题

我多次尝试更新Docker版本并重新启动Docker。但没起作用。

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'))

谢谢你们两位帮我解决错误！我试过推荐，但无法连接到我的码头：

Answer 1

你确定码头在你的系统上运行吗？当compose无法通过对接器套接字连接到对接器时(如果没有定义任何其他连接方式)，您可以得到该错误。

如果您在linux上运行，通常可以运行systemctl status docker来检查docker守护进程是否正在运行，而systemctl start docker是否正在启动它。

这将有助于判断您使用的是什么操作系统和docker version。

Answer 2

像这样设置许可，

sudo chmod 666 /var/run/docker.sock

Answer 3

使用时，WSL (Windows Linux子系统)需要在Windows码头桌面中为所需发行版启用“WSL集成”(Settings -> Resources-> WSL Integration ->启用与所需发行版的集成)。
