Question

我正在尝试使用 Python3.4 和 boto3 走一个 S3 存储桶并将一些文件位置发布到 RDS 实例。我遇到麻烦的部分工作是使用boto3。我的lambda函数如下所示：

import subprocess

def lambda_handler(event, context):
    args = ("venv/bin/python3.4", "run.py")
    popen = subprocess.Popen(args, stdout=subprocess.PIPE)
    popen.wait()
    output = popen.stdout.read()
    print(output)

并且，在我的 run.py 文件中，我有一些行：

import boto3

s3c = boto3.client('s3')

导致异常。然而， run.py 文件与此问题无关，所以为了使这篇文章更简洁，我发现执行lambda函数会产生此错误的原因：

import subprocess

def lambda_handler(event, context):
    args = ("python3.4", "-c", "import boto3; print(boto3.client('s3'))")
    popen = subprocess.Popen(args, stdout=subprocess.PIPE)
    popen.wait()
    output = popen.stdout.read()
    print(output)

我的日志流报告错误：

我需要在run.py的下游使用boto3。任何关于如何解决这个问题的想法都非常感谢。谢谢！

在AWS Lambda中的python3虚拟环境中使用boto3
