Your current KubeKey version

Version:"1.1.1", my system version is centos7.6.

Describe this feature

Hi, guys, I followed this document to try the "All-in-One Installation of Kubernetes and KubeSphere on Linux" https://v3-1.docs.kubesphere.io/zh/docs/quick-start/all-in-one-on-linux/#%e4%be%9d%e8%b5%96%e9%a1%b9%e8%a6%81%e6%b1%82

but I encounterd this issue, could somebody take a look? Thank you.

Describe the solution you'd like

Looks like the kubekey lost the kubeconfig?

Additional information

I tried to fix it by the following command, but issue still existed.

1.echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile

2. source ~/.bash_profile

You can try to delete the cluster ./kk delete cluster -f xxx.yaml and reinstall it.
