我从cert-manager中删除了其他版本。之后我用helm安装了新版本。
安装工作正常。
但是当我使用命令时：

$ kubectl get orders,challenges,clusterissuers

Error from server: request to convert CR from an invalid group/version: acme.cert-manager.io/v1alpha2
Error from server: request to convert CR from an invalid group/version: acme.cert-manager.io/v1alpha2
