我正在研究一个示例AWS项目,该项目创建了两个lambda函数。这些函数共享node_modules
中的公共代码,这些代码已放置在单独的层中(特别是AWS::Lambda::LayerVersion
,而不是AWS::Serverless::LayerVersion
)。我可以部署此代码,并且在测试已部署的版本时可以正常工作。
但是,当我尝试使用sam invoke local
在本地测试代码时,找不到通用代码。我收到此错误(我正在尝试使用npm包“ axios”):
{"errorType":"Runtime.ImportModuleError","errorMessage":"Error: Cannot find module 'axios'\nRequire stack:\n- /var/task/get-timezone.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js"}
这是我的template.yaml
:

ReverseFunctionIamRole:
Description: "Implicit IAM Role created for reverse function"
Value: !GetAtt ReverseFunctionRole.Arn
我正在像这样调用GetTimezone函数:
sam local invoke --layer-cache-basedir layer-cache --force-image-build \"GetTimezoneFunction\" --event events/event-timezone.json -d 5858
什么都不会复制到layer-cache
目录中,我敢肯定这是问题的一部分,但我不知道该如何解决。
我一直在寻找有关此问题的答案,但到目前为止,我仅找到未回答的问题或与我的情况不符的答案。
大多数与问题相关的问题涉及AWS::Serverless::LayerVersion
,而不涉及AWS::Lambda::LayerVersion
。我尝试改用Serverless
,但这没有帮助。
更新:
如果我改变...
Layers:
- !Ref SampleCommonLayer
...到...
Layers:
- arn:aws:lambda:us-east-2:xxxxxxxxxxxx:layer:SampleCommonLayer:y
...使用已部署的层(其中xxxxxxxxxxxx
和y
是特定的ID和版本),然后sam local invoke
起作用。但是我不想使用必须先部署的东西,我想使用最新的尚未部署的本地代码。

这是已知问题:https://github.com/awslabs/aws-sam-cli/issues/947
当前,“解决方法”是使用图层的目录而不是zip文件。
