Node.js lambda函数未找到lambda层中的铬

我开始尝试用node和puppeter编写lambda函数。我使用的是无服务器框架

我一直在努力按指示行事。我的功能在本地按预期工作，包括：

$ sls invoke local -f hello

按预期工作。然而，当我跑步时：

$ sls invoke -f hello

我得到：

$ sls invoke  -f hello
{
"errorType": "Error",
"errorMessage": "Cannot find module 'chr'\nRequire stack:\n- /var/task/index.js\n- /var/task/handler.js\n- /var/task/s_hello.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js",
"trace": [
    "Error: Cannot find module 'chr'",
    "Require stack:",
    "- /var/task/index.js",
    "- /var/task/handler.js",
    "- /var/task/s_hello.js",
    "- /var/runtime/UserFunction.js",
    "- /var/runtime/index.js",
    "    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:957:15)",
    "    at Module._require.o.require (/var/task/serverless_sdk/index.js:9:72748)",
    "    at require (internal/modules/cjs/helpers.js:77:18)",
    "    at Object.main (/var/task/index.js:47:26)",
    "    at module.exports.hello (/var/task/handler.js:6:25)",
    "    at Runtime.handler (/var/task/serverless_sdk/index.js:9:137040)",
    "    at Runtime.handleOnce (/var/runtime/Runtime.js:66:25)"
]

我怎样才能让它工作

My handler.js包含：

'use strict';
var index = require('./index.js');

module.exports.hello = async event => {
// var t = async event => {
  var res = await index.main();

  console.log('hello');
  console.log(res);

  console.log('IN HANDLER');
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'main function executed!',
        input: event,
     ......

async function main(event, context, callback) {

  const os = require('os');

  let result = null;
  let browser = null;

if (os.platform=='win32') {

  const puppeteer= require('puppeteer-core');
  browser = await puppeteer.launch({
    executablePath: 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe',
    headless: false,
    ignoreHTTPSErrors:true
  })
} else {
// launch a headless browser

  const chromeLambda = require('chrome-aws-lambda');
console.log(os.platform());  
console.log('lambda');  
browser = await chromeLambda.puppeteer.launch({
    args: chromeLambda.args,
    executablePath: await chromeLambda.executablePath,
    defaultViewport,
    headless:true 
  });





  var page = await browser.newPage();

   ........

};


module.exports.main = main;

my index.js包含：

'use strict';
var index = require('./index.js');

module.exports.hello = async event => {
// var t = async event => {
  var res = await index.main();

  console.log('hello');
  console.log(res);

  console.log('IN HANDLER');
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'main function executed!',
        input: event,
     ......

async function main(event, context, callback) {

  const os = require('os');

  let result = null;
  let browser = null;

if (os.platform=='win32') {

  const puppeteer= require('puppeteer-core');
  browser = await puppeteer.launch({
    executablePath: 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe',
    headless: false,
    ignoreHTTPSErrors:true
  })
} else {
// launch a headless browser

  const chromeLambda = require('chrome-aws-lambda');
console.log(os.platform());  
console.log('lambda');  
browser = await chromeLambda.puppeteer.launch({
    args: chromeLambda.args,
    executablePath: await chromeLambda.executablePath,
    defaultViewport,
    headless:true 
  });





  var page = await browser.newPage();

   ........

};


module.exports.main = main;

您是否为您的图层创建了“适当”的文件夹结构？例如

nodejs/nodel_modules/chrome aws lambda

？@Ersoy，我不明白您所说的“适当”是什么意思。lambda图层有一些约定，文件夹的名称应遵循此约定来注入/使用图层您创建了“适当”吗你的图层的文件夹结构？例如
