当前回答

我遇到过这样的问题几次,但每次都是因为我没有启动docker。 要解决这个问题,只需打开docker并等待它完成启动。

其他回答

我最近也有同样的问题。问题是安全软件(趋势科技)阻止docker创建Hyperv网络接口。你也应该检查防火墙,反病毒软件没有阻止安装或配置。

对我来说,问题是虚拟化没有启用。

在windows 10上:进入任务管理器->性能-> CPU,你应该看到“虚拟化:已启用”部分

如果您没有看到此选项,则意味着尚未启用虚拟化。

另一个要注意的有趣的事情是你必须启用Hyper V。然而,当我使用并行桌面时,我必须启用“嵌套虚拟化”,以使Hyper V“真正启用”。因此,如果您的windows是一个虚拟机,请检查Parallels(或任何您正在使用的)的设置,以启用嵌套虚拟化。

对我来说,在Windows 11上编辑%APPDATA%\Docker\settings。将json转换为以下值,然后重新启动Docker Desktop(我使用WSL2,而不是Hyper-V):

删除%appdata%\Docker下的文件夹,如Github问题所示

为了快速访问,按Ctrl+R,粘贴“%appdata%\Docker”,然后Enter,它应该打开一个文件夹位于appdata \Roaming\Docker(例如C:\Users\YourUsername\ appdata \Roaming\Docker)

在Windows 10机器上安装: 在安装搜索Windows功能之前,请先搜索并检查Windows hypervisor平台和Linux子系统

WSL 1或WSL 2的安装是强制性的,所以在docker提示您安装时安装它。

你需要从windows商店安装ubantu(版本16,18或20):

uhelp版本20

安装完成后,可以运行docker -version等命令 或docker在Linux终端运行hello-world。
