DynamoDB本地连接（HTTPConnectionPool（host ='localhost'，port = 8000））

Question

我想在DynamoDB中运行以下命令，但显示错误。我该如何解决这个问题？

$ aws dynamodb list-tables --endpoint-url http://localhost:8000

HTTPConnectionPool(host='localhost', port=8000): Max retries exceeded with url: / (Caused by NewConnectionError('<botocore.awsrequest.AWSHTTPConnection object at 0x7fa37950e0b8>: Failed to establish a new connection: [Errno 111] Connection refused',))
