python - 无法列出 s3 存储桶，出现类似“AttributeError: module 'boto3' has no attribute 'client'”的错误

Question

我收到如下错误：

AttributeError: module 'boto3' has no attribute 'client'

我的python片段如下所示

[ansible@ip-172-31-40-59 python]$ cat lists3buckets.py
#import boto3
#s3 = boto3.resource('s3')
#obj = s3.Object(bucketname, itemname)
#body = obj.get()['Body'].read()

#import boto3
#from botocore import ClientError
#s3 = boto3.client('s3')
#for bucket in s3.list_buckets():
#    print(bucket)

import boto3
from botocore.exceptions import ClientError
s3=boto3.client('s3')
for i in s3.list_buckets():
    print(i)

注意：我也尝试了注释代码，但没有运气。

我的环境是 Amazon Linux 2 机器，并且已经安装了 boto3 和 botocore。

[ansible@ip-172-31-40-59 python]$ pip3 install boto3 --upgrade --user

我正在执行如下脚本：

python3 lists3buckets.py
Traceback (most recent call last):
  File "lists3buckets.py", line 14, in <module>
    s3=boto3.client('s3')
AttributeError: module 'boto3' has no attribute 'client'

我不明白为什么一个简单的片段不应该工作？
