Cloud函数部署错误：函数在加载用户代码时失败。错误消息：文件lib / index.js中的代码无法加载

Question

我正在尝试添加Angular SSR，并创建了以下云函数：

import * as functions from 'firebase-functions';
import * as path from 'path';

const universal = require(path.resolve(__dirname, '../../dist/server/main')).app;

export const ssr = functions.https.onRequest(universal);

package.json

{
  "engines": {
    "node": "8"
  },
  "main": "lib/index.js",
  "dependencies": {
    "@types/jsdom": "^11.0.4",
    "firebase-admin": "^8.10.0",
    "firebase-functions": "^3.6.0",
    "path": "^0.12.7",
  },
  "devDependencies": {
    "typescript": "^3.8.3",
    "firebase-functions-test": "^0.2.1"
  }
}

当我构建然后部署我的函数时，我得到一个错误：

!  functions[ssr(us-central1)]: Deployment error.
Function failed on loading user code. Error message: Code in file lib/index.js can't be loaded.
Did you list all required modules in the package.json dependencies?

我的文件夹结构是：

dist
 |-server
 |-browser
functions
 |-lib

我该如何解决？

Answer 1

我猜测您的代码正在尝试访问“功能”文件夹之外的文件。也就是说，“ ../../ dist / server / main”正在到达该文件夹的边界之外。 Firebase CLI仅部署functions文件夹的内容。部署后，该功能将无法访问其以外的所有内容。如果您希望该内容可用，则必须将其复制到那里。是的，这也许意味着如果您在前端和后端都使用该文件，则必须复制该文件。
