    ✨  自动选择 docker 驱动。其他选项：none, ssh
    🛑  The "docker" driver should not be used with root privileges. If you wish to continue as root, use --force.
    💡  If you are running minikube within a VM, consider using --driver=none:
    📘    https://minikube.sigs.k8s.io/docs/reference/drivers/none/

    ❌  Exiting due to DRV_AS_ROOT: The "docker" driver should not be used with root privileges.

    此时直接使用minikube start命令，但是可能出现以下问题

    🧯  The requested memory allocation of 1987MiB does not leave room for system overhead (total system memory: 1987MiB). You may face stability issues.
    💡  建议：Start minikube with less memory allocated: 'minikube start --memory=1987mb'

    ❌  Exiting due to HOST_HOME_PERMISSION: Failed to save config: open /home/crayon/.minikube/profiles/minikube/config.json: permission denied
    💡  建议：Your user lacks permissions to the minikube profile directory. Run: 'sudo chown -R $USER $HOME/.minikube; chmod -R u+wrx $HOME/.minikube' to fix

    问题在于当前用户的权限不足导致的，原因可能是因为一开始使用了root用户执行了命令而以root用户创建了相关配置文件导致的，按照命令的提示信息修改文件的权限即可解决

    # 这里的文件路径默认是在当前用户的home目录下，需要将home目录路径改为你自己的home目录路径
    $ sudo chown -R crayon /home/crayon/.minikube; chmod -R u+wrx /home/crayon/.minikube

    改完权限再次执行启动命令

    启动之后会去拉去镜像，这个时候会发现镜像拉取的速度极慢

    建议使用中国区镜像拉取地址
