Kubectl 命令抛出错误：无法连接到服务器：获取凭据：exec：退出状态 2

我正在进行 EKS/Kubectl 的实验室设置，在完成集群构建后，我运行以下命令：

> kubectl get node

And I get the following error:
Unable to connect to the server: getting credentials: exec: exit status 2

此外，我确信这是一个配置问题，

kubectl version
usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:

  aws help
  aws <command> help
  aws <command> <subcommand> help
aws: error: argument operation: Invalid choice, valid choices are:

请告知后续故障排除步骤。
