当我在Mac（Mojave）的Mac上运行minikube --start时，尝试运行kubeadm init时会失败。
这是我运行的完整命令：
minikube start --logtostderr --stderrthreshold 0 -v 9
--cpus 2 --memory 4096 --disk-size=50g
--vm-driver=hyperkit
这是我得到的错误：

运行minikube logs时，我看到以下消息：
server.go:261] failed to run Kubelet: unable to load bootstrap kubeconfig: stat /etc/kubernetes/bootstrap-kubelet.conf: no such file or directory
如果我运行minikube ssh并列出/etc/kubernetes的内容，这是我看到的：
> cd /etc/kubernetes
> ls
addons manifests
对于minikube版本0.32.0和0.33.0，我会遇到相同的错误。
