安装kubectl 出现No such object: kubernetes-release/release//bin/darwin/amd64/kubectl

zhangze@ubuntu:~/Desktop$ kubectl client
/usr/local/bin/kubectl: line 1: syntax error near unexpected token `<'
/usr/local/bin/kubectl: line 1: `<?xml version='1.0' encoding='UTF-8'?><Error><Code>NoSuchKey</Code><Message>The specified key does not exist.</Message>
<Details>No such object: kubernetes-release/release//bin/darwin/amd64/kubectl</Details></Error>
