python2.7中的Boto3錯誤，但在3.5版中有效

Question

因此，我正在使用boto3訪問s3服務。 當我使用此代碼時，它可以在python3.5上正常工作，但在2.7中拋出此異常，為什么？ 我想用2.7來實現它，因為我的整個項目都基於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，拋出此異常：

Traceback (most recent call last):
  File "s3connector.py", line 22, in <module>
    s.createBucket('pqlamy1947621234')
  File "s3connector.py", line 15, in createBucket

查看錯誤消息，似乎並不是專門針對python版本的問題，因為Boto3開箱即用地支持Python 2.7。 因此，我做了一個快速檢查清單，該清單可能會（或不會）幫助您找到問題的原因

• 您是否在同一環境下嘗試過這兩個版本的Python？ 104錯誤可能來自多種原因，包括網絡和服務器端臨時問題。
• 您是否正在使用boto3的穩定版本？ 嘗試使用最新的穩定版本（在撰寫本文時為1.4.4 ）
• 如果以前的版本不起作用，請嘗試使用以前的穩定版本。 有時，舊版本中的這些錯誤是在較新版本中引入的。
• 如果所有方法均無效，請嘗試提交錯誤。 Boto團隊得到了Amazon的部分支持，並且對應用程序中斷問題做出了快速響應。
