Question

当EMR机器尝试运行包含boto3初始化的步骤时，有时会出现以下错误： ValueError: Invalid endpoint: https://s3..amazonaws.com 当我尝试安装新机器时，它可能突然工作。附有完整错误：

self.client = boto3.client("s3")
  File "/usr/local/lib/python3.6/site-packages/boto3/__init__.py", line 83, in client
    return _get_default_session().client(*args, **kwargs)
  File "/usr/local/lib/python3.6/site-packages/boto3/session.py", line 263, in client
    aws_session_token=aws_session_token, config=config)
  File "/usr/local/lib/python3.6/site-packages/botocore/session.py", line 861, in create_client
    client_config=config, api_version=api_version)
  File "/usr/local/lib/python3.6/site-packages/botocore/client.py", line 76, in create_client
    verify, credentials, scoped_config, client_config, endpoint_bridge)
  File "/usr/local/lib/python3.6/site-packages/botocore/client.py", line 285, in _get_client_args
    verify, credentials, scoped_config, client_config, endpoint_bridge)
  File "/usr/local/lib/python3.6/site-packages/botocore/args.py", line 79, in get_client_args
    timeout=(new_config.connect_timeout, new_config.read_timeout))
  File "/usr/local/lib/python3.6/site-packages/botocore/endpoint.py", line 297, in create_endpoint
    raise ValueError("Invalid endpoint: %s" % endpoint_url)
ValueError: Invalid endpoint: https://s3..amazonaws.com

知道为什么会发生吗？

（版本：boto3 == 1.7.29，botocore == 1.10.29）

Answer 1

您的区域似乎无效。 Check您的〜/ .aws / config

Answer 2

在~/.aws/credentials或~/.aws/config文件中设置区域。您还可以将区域设置为环境变量，例如

在bash

export AWS_REGION="eu-west-2"

或在Powershell

中

$Env:AWS_REGION="eu-west-2"

ValueError：无效的终结点：https：//s3..amazonaws.com
