Amplify部署Lambda遇Runtime.ImportModuleError：无法导入index模块

在Amplify创建的项目中，执行amplify push部署Lambda后，运行Lambda2时出现错误：[ERROR] Runtime.ImportModuleError: Unable to import module 'index'。

在被另一个Lambda异步调用的Lambda2中使用LangChain，从Pinecone获取结果并返回给前端的问题提问。

• 通过Amplify init创建Amplify项目
• 执行Amplify add api创建API Gateway及关联的Lambda1
• 执行Amplify add function创建异步Lambda2
• 执行amplify push部署时，Lambda2出现上述导入错误

pipenv未正确安装pinecone-client、langchain和requests包，注释掉这三个包后错误消失。

使用pipenv install重新安装pinecone-client、langchain和requests。
