Angular Firebase函数部署错误：找不到模块“firebase / app”。

Question

我将SSR添加到我的Angular Firebase项目中，并设置了WPA。成功部署在Firebase上（托管和功能）。但是下一次我在组件中编辑了一些代码。之后我进行了重新部署。Firebase托管正在成功部署，但是功能显示错误。 我正在使用Angular 8和package.json中的所有最新npm包。我还更新并重建了我的项目。在本地主机：5000上，一切正常工作。 我遇到的错误为： 功能无法加载用户代码。 错误消息：无法加载lib/index.js文件中的代码。

和 package.json

  "node": "8"
  },
  "main": "lib/index.js",
  "dependencies": {
  "@firebase/app": "^0.4.15",
  "firebase-admin": "^8.0.0",
  "firebase-functions": "^3.1.0"
   },
   "devDependencies": {
   "tslint": "^5.12.0",
   "typescript": "^3.2.2"
  },

并且index.js函数：

   import * as functions from 'firebase-functions';


   const universal = require(`${process.cwd()}/dist/server`).app;


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

在命令行上输入：firebase log 获取到：

Did you list all required modules in the package.json dependencies?

我已经到处寻找解决方案，但没有找到。

进入 /functions 目录并运行：

$ sudo npm install --save firebase @angular/fire -f   

如果无法解决你的问题，你可以在/functions目录中删除node_modules文件夹，并使用我的依赖项：

functions/package.json

"dependencies": {
    "firebase-admin": "^8.0.0",
    "firebase-functions": "^3.1.0",
    "@angular/animations": "~8.2.3",
    "@angular/common": "~8.2.3",
    "@angular/compiler": "~8.2.3",
    "@angular/core": "~8.2.3",
    "@angular/fire": "^5.2.1",
    "@angular/forms": "~8.2.3",
    "@angular/platform-browser": "~8.2.3",
    "@angular/platform-browser-dynamic": "~8.2.3",
    "@angular/platform-server": "~8.2.3",
    "@angular/router": "~8.2.3",
    "@ng-bootstrap/ng-bootstrap": "^5.1.0",
    "bootstrap": "^4.0.0-alpha.6",
    "compression": "^1.7.4",
    "firebase": "^6.4.2",
    "rxjs": "~6.4.0",
    "tslib": "^1.10.0",
    "xmlhttprequest": "^1.8.0",
    "zone.js": "~0.9.1"
  }

运行npm install，然后将您的应用程序部署到Firebase时它应该可以工作。
