带有AWS Lambda错误的“无服务器框架"“无法找到模块"；

问题描述

我正在尝试使用无服务器框架来创建使用开放天气NPM模块的Lambda函数.但是，出现以下异常，但是我的node_modules包含特定的库.

I'm trying to use the Serverless Framework to create a Lambda function that uses open weather NPM module. However, I'm getting the following exception, but my node_modules contain the specific library.

我设法运行了示例，( https://github.com/serverless/examples/tree/master/aws-node-rest-api-with-dynamodb )，现在正在黑客添加节点模块以集成开放天气API.

I have managed to run the sample, (https://github.com/serverless/examples/tree/master/aws-node-rest-api-with-dynamodb) successfully, now hacking to add node module to integrate open weather API.

Endpoint response body before transformations: {"errorMessage":"Cannot find module 'Openweather-Node'","errorType":"Error","stackTrace":["Module.require (module.js:353:17)","require (internal/module.js:12:17)","Object.<anonymous> (/var/task/todos/weather.js:4:17)","Module._compile (module.js:409:26)","Object.Module._extensions..js

我的代码

'use strict';

  const AWS = require('aws-sdk'); // eslint-disable-line import/no-extraneous-dependencies
  var weather = require('Openweather-Node');

  const dynamoDb = new AWS.DynamoDB.DocumentClient();

  module.exports.weather = (event, context, callback) => {
    const params = {
      TableName: process.env.DYNAMODB_TABLE,
      Key: {
        id: event.pathParameters.id,
      },
    };

    weather.setAPPID("mykey");
    //set the culture
    weather.setCulture("fr");
    //set the forecast type
    weather.setForecastType("daily");

    const response = {
      statusCode: 200,
      body: "{test response}",
    };
    callback(null, response);
  };

推荐答案

在执行serverless deploy之前，您是否在工作目录中已经npm install? aws-sdk节点模块可用于所有lambda函数，但是对于所有其他节点依赖项，您必须安装它们，以便在部署时将它们与lambda打包在一起.

Did you npm install in your working directory before doing your serverless deploy? The aws-sdk node module is available to all lambda functions, but for all other node dependencies you must install them so they will be packaged with your lambda when you deploy.
