Minikube Kubernetes kubectl MacOS的错误

我只是按照说明我的Mac上使用BREW安装Minikube：Minikube Kubernetes kubectl MacOS的错误

https://github.com/kubernetes/minikube 

brew cask install minikube

然后，我只是按照说明进行测试：

minikube start

给我的以下：

MacBook-Pro:~ joe$ minikube start 
Starting local Kubernetes v1.6.4 cluster... 
Starting VM... 
Moving files into cluster... 
Setting up certs... 
Starting cluster components... 
Connecting to cluster... 
Setting up kubeconfig... 
Kubectl is now configured to use the cluster

然后我试着问了kubectl版本：

MacBook-Pro:~ joe$ kubectl version 
Client Version: version.Info{Major:"1", Minor:"4", GitVersion:"v1.4.5", GitCommit:"5a0a696437ad35c133c0c8493f7e9d22b0f9b81b", GitTreeState:"clean", BuildDate:"2016-10-29T01:38:40Z", GoVersion:"go1.7.1", Compiler:"gc", Platform:"darwin/amd64"} 
Server Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.4", GitCommit:"d6f433224538d4f9ca2f7ae19b252e6fcb66a3ae", GitTreeState:"dirty", BuildDate:"2017-06-22T04:31:09Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}

然后，我试过如下平时Hello World示例，导致错误（如下所示）：

MacBook-Pro:~ joe$ kubectl run hello-minikube --image=gcr.io/google_containers/echoserver:1.4 --port=8080 
error: group map[extensions:0xc4204c6000 policy:0xc4204c6070 rbac.authorization.k8s.io:0xc4200ea070 storage.k8s.io:0xc4200ea150 federation:0xc4203ba0e0 apps:0xc4203ba620 authentication.k8s.io:0xc4203ba690 batch:0xc4203baa10 certificates.k8s.io:0xc4203baa80 componentconfig:0xc4203baaf0 :0xc4203ba5b0 authorization.k8s.io:0xc4203ba7e0 autoscaling:0xc4203ba850] is already registered

我找不到任何合适的答案。我想我的kubectl客户端应该更新。但是，我如何在Mac上执行此操作？我想这是使用brew安装的。那么，我有什么想法可以解决这个问题？

编辑：试了一下从塞巴斯蒂安Goasguen

赫斯的职位是什么，我得到：
