Minikube Kubernetes kubectl MacOS的錯誤

我只是按照說明我的Mac上使用BREW安裝Minikube：Minikube Kubernetes kubectl MacOS的錯誤

https://github.com/kubernetes/minikube 

brew cask install minikube

然後，我只是按照說明進行測試：

minikube start

給我的以下：

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

然後我試着問了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"}

然後，我試過如下平時Hello World示例，導致錯誤（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

我找不到任何合適的答案。我想我的kubectl客戶端應該更新。但是，我如何在Mac上執行此操作？我想這是使用brew安裝的。那麼，我有什麼想法可以解決這個問題？

編輯：試了一下從塞巴斯蒂安Goasguen

赫斯的職位是什麼，我得到：
