curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=v1.19.5+k3s1 K3S_KUBECONFIG_MODE="644" sh -
它安装成功。

但是当我运行以下 helm add repo 命令时，会出现连接超时错误消息。我还导出了 kubeconfig 文件export KUBECONFIG=~/.kube/config。
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts

当我运行helm list命令时，显示以下消息。

当我运行helm list命令时，会显示以下消息。

成功添加 helm repo 以解决此问题的任何想法。预先感谢。
