解决方法

根据报错信息，可以看出程序无法下载所需文件：kube-proxy_v1.22.2
需要解决上面提示的那个问题：
! This container is having trouble accessing https://k8s.gcr.io
* To pull new external images, you may need to configure a proxy: https://minikube.sigs.k8s.io/docs/reference/networking/proxy/
这是网络的问题，国内不允许访问 ！
使用国内阿里的镜像仓库进行安装：

minikube delete  # 必需先清除缓存后再继续，否则问题不会得到解决
minikube start --image-mirror-country='cn' --driver docker --image-repository=registry.cn-hangzhou.aliyuncs.com

# 也可以如下：
minikube config set driver docker
minikube config set image-repository registry.cn-hangzhou.aliyuncs.com
minikube delete
minikube start

问题已得到解决：

[minikube@slave4 ~]$ minikube delete

! /usr/local/bin/kubectl is version 1.8.0, which may have incompatibilites with Kubernetes 1.22.2.
  - Want kubectl v1.22.2? Try 'minikube kubectl -- get pods -A'
* Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default
