Question

我一直在尝试使用serverless-offline / serverless-offline-python和其他一系列节点程序包（例如serverless-s3-local）为我已经使用过的某些lambda构建离线测试环境

使用serverless-offline-python，我可以启动python lambda，并使用以下命令手动调用每个函数：

sls offline start --stage local --noTimeout --watch --port 3000
sls invoke local --stage local -f import-processor-stage-1 -d '{"event": "", "context": ""}'

这有效，但是并不能完全模拟lambda实际在做什么。理想情况下，我将模拟一个导入了新对象的S3存储桶，该动作将成为lambda（import-processor-stage-1）的催化剂。

Enter serverless-s3-local。

我使用该插件进行了非常出色的配置，但是由于某种原因，当serverless-s3-local触发我的lambda处理程序事件时，我收到此错误：

可悲的是，我知道这些插件尚处于起步阶段（尤其是serverless-offline-python），但我非常确定这应该是一个非常简单的修复程序。软件包中实际上存在未找到的模块！我认为这是因为它是一个Python文件而不是JS文件。 js脚本中是否可以接受python文件？到目前为止，我已经尝试在serverless-offline代码库中将serverless-offline-python的所有引用替换为serverless-s3-local，但是遇到相同的错误。

作为参考，这是我的serverless.yml文件（作为记录，该处理程序文件可用，正确定位并且在手动调用它时可以正常工作）：

任何帮助都将受到赞赏！谢谢您的光临！

可以确认这适用于js环境。

我最终定制了serverless-s3-local库以能够调用.py文件。我可能最终会为此自定义创建一个新的github repo和node包，但是现在我将引导用户参考我所描述的here的自定义。
