问题描述

在此处输入图像描述

我正在尝试使用 netlify 及其 lambda 函数功能来运行具有依赖关系的节点函数。基于https://css-tricks.com/using-netlify-forms-and-netlify-functions-to-build-an-email-sign-up-widget/,我有我的函数/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}`)
    ....

当我查看我的 netlify 网站功能选项卡(上面的截图)时,我看到:

11:40:35 PM: 2020-12-02T04:40:35.092Z   undefined   ERROR   Uncaught Exception  {"errorType":"Runtime.ImportModuleError","errorMessage":"Error: Cannot find module 'node-fetch'\nRequire stack:\n- /var/task/submission-created.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js","stack":["Runtime.ImportModuleError: Error: Cannot find module 'node-fetch'","Require stack:","- /var/task/submission-created.js","- /var/runtime/UserFunction.js","- /var/runtime/index.js","    at _loadUserApp (/var/runtime/UserFunction.js:100:13)","    at Object.module.exports.load (/var/runtime/UserFunction.js:140:17)","    at Object.<anonymous> (/var/runtime/index.js:43:30)","    at Module._compile (internal/modules/cjs/loader.js:1015:30)","    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1035:10)","    at Module.load (internal/modules/cjs/loader.js:879:32)","    at Function.Module._load (internal/modules/cjs/loader.js:724:14)","    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:60:12)","    at internal/main/run_main_module.js:17:47"]}

我的 package.json (运行 npm init 之后):

{
"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"
}
 }

包结构如下:

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,但我仍然收到上述错误。我究竟做错了什么?

解决方案


我认为这个错误有很多原因,我今天得到它并尝试了一些解决方案Error: Cannot find module 'node-fetch'" when deploying function ; Netlify 函数找不到模块;并且不能在 lambda 函数中使用 node-fetch

  • 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functions/testfunc/package.json将命令更改netlify.tomlcd functions/testfunc && npm install && cd ../../ && npm build
  • 将 const 更改fetch = require('node-fetch')为:
    • const fetch = require('node-fetch').default
    • const fetch = request('node-fetch').default
  • 添加node-fetch的对等依赖项encoding

然而,这些都没有奏效。然后,我尝试查看从 Netlify 函数游乐场复制Fetch示例是否可行,并且确实可行。问题是我的函数中有一个名为static

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

由于某种原因,有一个称为静态原因的变量

Error: Cannot find module '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。
