转换失败:某些目录没有执行权限 [英] Conversion failed: Some directories do not have execute permissions

问题描述

我正在尝试在 AWS CloudFormation 中创建 AWS Lambda层，但发生错误:

I am trying to create a AWS Lambda Layer in AWS CloudFormation but happens an error:

层转换失败:某些目录没有执行权限；(服务:AWSLambdaInternal；状态代码:400；错误代码:InvalidParameterValueException；请求ID:eff63297-bf71-4578-a665-c493a9fbdb40)

Layer conversion failed: Some directories do not have execute permissions; (Service: AWSLambdaInternal; Status Code: 400; Error Code: InvalidParameterValueException; Request ID: eff63297-bf71-4578-a665-c493a9fbdb40)

CloudFormation模板中的Lambda层定义:

Lambda Layer definition in CloudFormation Template:

LambdaLayerTest:
  Type: 'AWS::Lambda::LayerVersion'
  Properties:
    CompatibleRuntimes: 
      - nodejs8.10
    Content:
      S3Bucket: cf-us-west-2-test
      S3Key: LambdaLayerTest.zip
    Description: Lambda Layer Test
    LayerName: lambdalayertest

LambdaLayerTest.zip是一个名为"nodejs"的文件夹，其中包含node_modules文件夹，package.json文件和yarn.lock文件.

LambdaLayerTest.zip is a folder named "nodejs" with node_modules folder, package.json file and yarn.lock file.

package.json:

package.json:

{
  "name": "mylayertest",
  "version": "1.0.0",
  "main": "index.js",
  "license": "ISC",
  "dependencies": {
     "aws-sdk": "2.307.0"
}

推荐答案

压缩文件夹中的文件权限对于AWS Lambda可能过于严格:

The file permissions in your zipped folder may be too restrictive for AWS Lambda:

关于Lambda部署软件包的权限政策

运行 chmod -R 755< directory> 会以递归方式修改所有子目录和文件的读取，写入和执行权限.

Running chmod -R 755 <directory> modifies read, write, and execute permissions recursively on all subdirectories and files.
