Question

当我尝试连接redshift集群时遇到错误。

我已经导入了所有用于在lambda上运行python代码的库。运行Python代码会产生错误。

import json
import boto3
import os
import psycopg2
import base64
from datetime import datetime
import logging
import sys
import hashlib
import urllib
import platform


def lambda_test():
    print('hello')
    conn_string = "dbname='dev' port='5439' user='my-user' password='my-password' host='redshift-cluster-1.calcocahphdx.us-east-1.redshift.amazonaws.com:5439'"
    conn = psycopg2.connect(conn_string)

def lambda_handler(event, context):
    # TODO implement
    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }

lambda_test()

响应：

{
  "errorMessage": "module initialization error"
}

使用Lambda和psycopg2连接到Redshift时模块初始化错误
