AWS lambda:没有名为“cfnresponse"的模块

问题描述

我已经部署了一个 AWS lambda，其中包含:

I have deployed an AWS lambda which contains:

import json
import boto3
import cfnresponse
import urllib.request
from botocore.exceptions import ClientError

def lambda_handler(event, context):
...
cfnresponse.send(event, context, status, responseData, "CustomResourcePhysicalID")

我试图在我的 cloudformations 中获取 cfnresponse 的值:

I tried to get the values of the cfnresponse in my cloudformations:

Resources:
  API:
    Type: Custom::API
    Version: '1.0'
    Properties:
      ServiceToken: arn:aws:lambda:eu-west-1:1234567891011:function:getCountry
Outputs:
  Status:
    Value:
       !GetAtt API.Data

现在 cfn 卡住了，我收到了错误:

Now th cfn is stuck and I got the error:

Unable to import module 'lambda_function': No module named 'cfnresponse' 

我做错了什么?当我查看 文档.

What am I doing wrong? It seems the way to do it when I check the docs.

推荐答案

Cfnresponse 在 Python 2.7 中默认仅在 lambda 中可用.可能您使用的是 3.6.

Cfnresponse is just available in lambda by default with python 2.7. Probably you are using 3.6.
