ImportModuleError"，"errorMessage":“错误:在将Netlify lambda函数与依赖项一起使用时找不到模块 [英] ImportModuleError","errorMessage":"Error: Cannot find module while using Netlify lambda functions with dependencies

问题描述

我正在尝试使用netlify及其lambda函数功能来运行具有依赖项的节点函数.基于

这是仓库:

  https://github.com/kc1/test2 

我尝试将节点模块文件夹和package.json放在多个位置并重新推送存储库，但是我仍然遇到上述错误.我在做什么错了?

请参见 Netlify:未找到构建命令，继续发布获取有关构建过程的新信息

解决方案

我认为此错误有很多原因，今天我明白了，并尝试了; Netlify函数找不到模块；和无法在lambda函数中使用节点获取

• 在项目根目录中安装依赖项
• 在特定于功能的文件夹中安装deps，例如具有 functions/testfunc/package.json 并将 netlify.toml 中的命令更改为 cd functions/testfunc&&npm安装&&cd ../../&&npm build
• 将const fetch = require('node-fetch')更改为:
  • const fetch = require('node-fetch').default
  • const fetch = request('node-fetch').default
• 添加 node-fetch 的对等依赖项 encoding

但是，这些都不起作用.然后，我尝试查看是否可以从Netlify函数游乐场复制获取示例是否可以正常工作.问题是我的函数中有一个名为 static

的变量

  const static = ['/blog'，'/about'，'/']; 

由于某种原因，有一个名为 static 的变量会导致

 错误:找不到模块'node-fetch' 

我不知道为什么，但是将其更改为其他内容可以解决此问题.

I'm trying to use netlify and its lambda function feature to run a node function with dependencies. Based on https://css-tricks.com/using-netlify-forms-and-netlify-functions-to-build-an-email-sign-up-widget/ , I have in my functions/submission-created.js:

const fetch = require('node-fetch');

exports.handler = async event => {

    const email = JSON.parse(event.body).payload.EMAIL
    const asking = JSON.parse(event.body).payload.ASKING
    console.log(`Recieved a submission: ${email}`)
    ....

When I look under my netlify websites functions tab (secreenshot above) , I see:

my package.json (after running npm init):

{
"name": "site",
"version": "1.0.0",
"description": "",
"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
 },
"author": "",
"license": "ISC",
"dependencies": {
  "dotenv": "^8.2.0",
  "node-fetch": "^2.6.1"
}
 }

The package structure looks like:

here is the repo :

https://github.com/kc1/test2

I've tried putting the node modules folder and package.json in multiple places and repushing the repo, but I'm still getting the error above. What am I doing wrong?

EDIT:

please see Netlify: No build command found, continuing to publishing for new info on build process

解决方案

I think there's lots of reason for this error, I got it today and tried some solutions from Error: Cannot find module ‘node-fetch’" when deploying function;Netlify Functions Can't find module; and Cannot use node-fetch in lambda function

• Installing dependencies in project root
• Installing deps in functions specific folder e.g. having functions/testfunc/package.json and changing command in netlify.toml to cd functions/testfunc && npm install && cd ../../ && npm build
• Changing const fetch = require('node-fetch') to:
  • const fetch = require('node-fetch').default
  • const fetch = request('node-fetch').default
• Adding node-fetch's peer dependency encoding

However, none of these things worked. I then tried seeing if copying the Fetch example from Netlify functions playground would work and it did. The issue was that I had a variable in my function called static

const static = ['/blog', '/about', '/'];

For some reason having a variable called static causes

Error: Cannot find module 'node-fetch'

I don't know why but changing this to something else fixed the issue.
