python2.7中的Boto3错误，但在3.5版中有效

Question

因此，我正在使用boto3访问s3服务。 当我使用此代码时，它可以在python3.5上正常工作，但在2.7中抛出此异常，为什么？ 我想用2.7来实现它，因为我的整个项目都基于2.7。

import boto3

conn = boto3.resource('s3', region_name='eu-west-1', endpoint_url=HOST, aws_access_key_id=KEY, aws_secret_access_key=SECRET)

conn.create_bucket(Bucket="pqlamy194762123")

在2.7中，抛出此异常：

Traceback (most recent call last):
  File "s3connector.py", line 22, in <module>
    s.createBucket('pqlamy1947621234')

查看错误消息，似乎并不是专门针对python版本的问题，因为Boto3开箱即用地支持Python 2.7。 因此，我做了一个快速检查清单，该清单可能会（或不会）帮助您找到问题的原因

• 您是否在同一环境下尝试过这两个版本的Python？ 104错误可能来自多种原因，包括网络和服务器端临时问题。
• 您是否正在使用boto3的稳定版本？ 尝试使用最新的稳定版本（在撰写本文时为1.4.4 ）
• 如果以前的版本不起作用，请尝试使用以前的稳定版本。 有时，旧版本中的这些错误是在较新版本中引入的。
• 如果所有方法均无效，请尝试提交错误。 Boto团队得到了Amazon的部分支持，并且对应用程序中断问题做出了快速响应。
