Ubuntu 22.04环境下AWSPowerShellLambdaPackage打包失败求助

问题场景 #

在AWS EC2的Ubuntu 22.04实例上，已配置AWS凭证，执行以下命令打包PowerShell脚本为Lambda包时失败：

New-AWSPowerShellLambdaPackage -ScriptPath test.ps1 -OutputPackage test.zip

解决方案 #

按以下步骤逐一排查解决：

• 确保输出目录存在且权限充足
  报错中输出路径为/home/ubuntu/test/Scripts/lamda_package/test.zip，先确认目录存在并赋予当前用户读写权限：

  mkdir -p /home/ubuntu/test/Scripts/lamda_package
  chown -R ubuntu:ubuntu /home/ubuntu/test/Scripts/lamda_package
  

• 明确指定FunctionArchitecture参数
  AWSLambdaPSCore 4.x版本需要明确指定架构，避免默认值不兼容。根据EC2实例架构选择x86_64或arm64：

  New-AWSPowerShellLambdaPackage -ScriptPath ../Scripts/test.ps1 -OutputPackage ../Scripts/lamda_package/test.zip -FunctionArchitecture x86_64
  

• 更新AWSLambdaPSCore模块至最新版本
  当前使用的4.0.0.0版本可能存在已知问题，更新到最新版本：

  Update-Module AWSLambdaPSCore -Force
  

• 手动安装.NET Lambda工具
  确保依赖的.NET Lambda工具完整安装：

  dotnet tool install -g Amazon.Lambda.Tools
  

  安装完成后重启PowerShell再执行打包命令。

• 使用绝对路径替代相对路径
  避免相对路径解析错误，改用绝对路径指定脚本和输出包：

  New-AWSPowerShellLambdaPackage -ScriptPath /home/ubuntu/test/Scripts/test.ps1 -OutputPackage /home/ubuntu/test/Scripts/lamda_package/test.zip -FunctionArchitecture x86_64
  

• 开启详细日志定位问题
  添加-Verbose参数获取更详细的错误信息，便于定位具体失败原因：

  New-AWSPowerShellLambdaPackage -ScriptPath ../Scripts/test.ps1 -OutputPackage ../Scripts/lamda_package/test.zip -Verbose
