python2.7中的Boto3错误，但在3.5版中有效

Question

So I'm using boto3 to access a s3 service. When I use this code it works fine with python3.5 but throws this exception in 2.7, why? I would like to implement it with 2.7 because my whole project is based on 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")

With 2.7 this exception is thrown:

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

Answer 1

Looking at the error message it doesn't seem to be an issue related specifically to the python version, as Boto3 supports Python 2.7 out of the box. So I made a quick checklist that may (or not) help you find the cause of your problem

• Have you tried both versions of Python under the same environment? 104 errors can have a variety of sources, including networking and server-side temporary issues.
• Are you using a stable version of boto3 ? Try using the latest stable version ( 1.4.4 as I'm writing this)
• If the previous doesn't work, try using a previous stable version. Some times these bugs with legacy environments are introduced with newer releases.
• If none of it works, try filing a bug. The boto team is partially supported by Amazon and responds quite quickly to app-breaking issues.
