【问题描述】：

我正在尝试使用 netlify 及其 lambda 函数功能来运行节点函数。基于https://css-tricks.com/using-netlify-forms-and-netlify-functions-to-build-an-email-sign-up-widget/。

我无法让节点模块工作（请参阅ImportModuleError","errorMessage":"Error: Cannot find module while using Netlify lambda functions with dependencies）

我刚刚意识到有一个部署日志，其中包含：

2:53:02 PM: Build ready to start
12:53:03 PM: build-image version: 8e31xxxxxxx
12:53:03 PM: build-image tag: v2.8.2

12:53:05 PM: Different functions path detected, going to use the one specified in the toml file: './functions' versus '' in the site
12:53:05 PM: No build command found, continuing to publishing
12:53:05 PM: Starting to deploy site from '/'

我的 netlify.toml 只有以下内容：

[build]
  functions = "./functions"

我是否应该添加其他内容以允许使用节点依赖项？

编辑：

我的 package.json：

"name": "test2",
"version": "1.0.0",
"description": "",
"scripts": {
 "test": "echo \"Error: no test specified\" && exit 1",

 },
 "repository": {
 "type": "git",
 "url": "git+https://github.com/kc1/test2.git"
 },
"keywords": [],
"author": "",
"license": "ISC",
"bugs": {
"url": "https://github.com/kc1/test2/issues"
 } ,
"homepage": "https://github.com/kc1/test2#readme",
"dependencies": {
"dotenv": "^8.2.0",
"node-fetch": "^2.6.1"

} }

我意识到我没有构建脚本。你应该推荐什么？我尝试构建：'npm run build'，但这导致构建失败..

【解决方案1】：

这是来自Express 的博客文章，但应该是相似的。

netlify.toml 看起来像这样：

[build]
  command = "npm install && npm run build"
  functions = "functions"

确保您的 package.json 实际上有构建命令。

如果您真的花时间阅读我为package.json 提供的链接，您会发现您的package.json 不包含构建命令。 npm run build: runs the build field from the package.json scripts field. stackoverflow.com/a/53311374/3850405 package.json 来自我链接到的 Github，例如：github.com/neverendingqs/netlify-express/blob/master/…
我阅读了所有的链接。我来自 python 背景，对 package.json 和 node 中的构建过程不太了解。我意识到我的 package.json 不包含构建脚本，但我不明白其中的构建脚本使用什么。我尝试将 "build": "npm run build" 添加到 package.json 产生 app.netlify.com/sites/inspiring-ardinghelli-4a4da5/deploys/… 。你会在这里推荐什么？
npm run build 映射到 package.json -> scripts -> build。给定示例，他们有一个构建脚本可以执行"build": "netlify-lambda build express",。请查看这个完整的示例，并在继续之前了解其中的所有内容，这将是我最好的建议。 gist.github.com/skatkov/b524a6e60a5313acc4d299471a2a3902
