我正在开发一个创建两个 lambda 函数的示例 AWS 项目。这些函数共享公共代码,这些代码node_modules
已放置在单独的层中(具体来说AWS::Lambda::LayerVersion
,不是AWS::Serverless::LayerVersion
)。我可以部署此代码,并且在我测试部署的版本时它可以正常工作。
但是,当我尝试在本地使用 测试代码时sam invoke local
,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:

我正在调用 GetTimezone 函数,如下所示:
sam local invoke --layer-cache-basedir layer-cache --force-image-build \"GetTimezoneFunction\" --event events/event-timezone.json -d 5858
没有任何东西被复制到layer-cache
目录中,我确信这是问题的一部分,但我不知道如何解决这个问题。
我已经搜索过这个问题的答案,但到目前为止,我只找到了未回答的问题,或者与我的特定情况不匹配的答案。
大多数有点相关的问题涉及AWS::Serverless::LayerVersion
,而不是AWS::Lambda::LayerVersion
。我尝试过使用Serverless
,但这并没有帮助。
更新:
如果我改变...
Layers:
- !Ref SampleCommonLayer
...至...
Layers:
- arn:aws:lambda:us-east-2:xxxxxxxxxxxx:layer:SampleCommonLayer:y
...使用已经部署的层(其中xxxxxxxxxxxx
和y
是特定的 ID 和版本)然后sam local invoke
工作。但是我不想使用我必须先部署的东西,我想使用最新的本地尚未部署的代码。
