二：报错原因
calico版本 与 k8s版本不匹配
查看k8s的版本
kubectl version
文章来源地址https://uudwc.com/A/v0gzR
查看k8s对应的calico的版本 https://projectcalico.docs.tigera.io/archive/v3.20/getting-started/kubernetes/requirements
查看需要v3.2.0的版本的calico
三.解决方案
重新下载正确版本calico
curl https://docs.projectcalico.org/v3.20/manifests/calico.yaml -O
再执行
kubectl apply -f calico.yaml
可以看到以下效果，代表成功了
