Runtime.ImportModuleError:无法导入模块“lambda_function”:没有名为“httplib2”的模块

5 python google-api amazon-web-services aws-lambda aws-lambda-layers

我已经安装了所有这些库:

google-api-core 1.22.1
google-api-python-client 1.10.0
google-auth 1.20.1
google-auth-httplib2 0.0.4
google-auth-oauthlib 0.4.1
google-cloud 0.34.0
google-cloud-core 1.4.1
google-cloud-storage 1.31.0
google-crc32c 1.0.0
google-resumable-media 1.0.0
googleapis-common-protos 1.52.0
httplib2 0.18.1

到一个文件夹 --> 压缩它 --> 上传到 AWS lambda 的层。然而,当我[ERROR] Runtime.ImportModuleError: Unable to import module 'lambda_function': No module named 'httplib2'在本地运行我的 pyhon 文件且此类库位于环境中时,我不断地思考,在调用import httplib2. 注意:所有其他库都适用于 lambda,因此我的上传过程应该是正确的。

您可以使用您的包创建 Lambda自定义层

为了检查这个解决方案,我创建了这样一个层并可以确认它是否有效

使用的技术包括最近的AWS 博客中描述的docker 工具

于是针对这个问题,我验证 如下:

  1. 创建空文件夹,例如mylayer.

  2. 转到该文件夹​​并创建requirements.txt包含以下内容的文件

google-api-core==1.22.1
google-api-python-client==1.10.0
google-auth==1.20.1
google-auth-httplib2==0.0.4
google-auth-oauthlib==0.4.1
google-cloud==0.34.0
google-cloud-core==1.4.1
google-cloud-storage==1.31.0
google-crc32c==1.0.0
google-resumable-media==1.0.0
googleapis-common-protos==1.52.0
httplib2==0.18.1

  1. 运行以下 Docker 命令:
docker run -v "$PWD":/var/task "lambci/lambda:build-python3.8" /bin/sh -c "pip install -r requirements.txt -t python/lib/python3.8/site-packages/; exit"

  1. 创建图层为 zip:
zip -r -9 mylayer.zip python

  1. mylayer.zip在AWS控制台中创建基于的lambda层。不要忘记指定Compatible runtimespython3.8.

  2. 使用以下 lambda 函数测试 lambda 中的层:

import httplib2

def lambda_handler(event, context):
    # TODO implement
    print(dir(httplib2))
    return
