当我简单地运行下面的代码时,我总是得到这个错误。
s3 = boto3.resource('s3')
bucket_name = "python-sdk-sample-%s" % uuid.uuid4()
print("Creating new bucket with name:", bucket_name)
s3.create_bucket(Bucket=bucket_name)
我已将我的证书文件保存在
C:\Users\myname\.aws\证书,从那里Boto应该读我的证书。
我的设置错了吗?
下面是boto3的输出。set_stream_logger (botocore,级别=“调试”)。

确保你的~/。Unix中的aws/credentials文件是这样的:
[MyProfile1]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey
[MyProfile2]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey
你的Python脚本应该是这样的,它可以工作:
from __future__ import print_function
import boto3
import os
os.environ['AWS_PROFILE'] = "MyProfile1"
os.environ['AWS_DEFAULT_REGION'] = "us-east-1"
ec2 = boto3.client('ec2')
# Retrieves all regions/endpoints that work with EC2
response = ec2.describe_regions()
print('Regions:', response['Regions'])

如果在~/中有多个aws配置文件。aws /凭证等……
[Profile 1]
aws_access_key_id = *******************
aws_secret_access_key = ******************************************
[Profile 2]
aws_access_key_id = *******************
aws_secret_access_key = ******************************************
遵循两个步骤:
在终端中使用export AWS_DEFAULT_PROFILE=Profile 1命令创建一个您想使用的默认值。
请确保在使用boto3或打开编辑器的同一终端上运行上述命令。[理解以下场景]
场景:
如果有两个终端,分别是t1和t2。
然后在t1中运行export命令,然后从t2中打开JupyterLab或任何其他命令,您将得到NoCredentialsError: Unable to locate credentials错误。
解决方案:
在t1中运行export命令,然后从同一终端t1打开JupyterLab或任何其他命令。
