TS2688：找不到安装了@ types / node的'node'的类型定义文件

我很难在Heroku上构建TypeScript应用程序。

我的依赖项列表包含我正在使用的所有包的类型定义：

"dependencies": {
    "@nestjs/common": "^4.5.1",
    "@nestjs/core": "^4.5.1",
    "@nestjs/microservices": "^4.5.1",
    "@nestjs/testing": "^4.5.1",
    "@nestjs/websockets": "^4.5.1",
    "@types/express": "^4.0.39",
    "@types/jest": "^21.1.8",
    "@types/json-schema": "^6.0.0",
    "@types/jsonwebtoken": "^7.2.5",
    "@types/mongoose": "^4.7.29",
    "@types/node": "^8.5.1",
    "@types/passport": "^0.4.2",
    "@types/passport-jwt": "^3.0.0",
    "@types/supertest": "^2.0.4",
    "chalk": "^2.3.0",
    "dotenv": "^4.0.0",
    "express-jwt": "^5.3.0",
    "global": "^4.3.2",
    "jsonwebtoken": "^8.1.0",
    "mongoose": "^4.13.7",
    "passport": "^0.4.0",
    "passport-jwt": "^3.0.1",
    "redis": "^2.8.0",
    "reflect-metadata": "^0.1.10",
    "rxjs": "^5.5.5",
    "tslint": "^5.8.0",
    "ts-node": "^4.0.2",
    "typescript": "^2.6.2"
  },

然而，当在Heroku上构建时，我得到：

error TS2688: Cannot find type definition file for 'node'
error TS2307: Cannot find module 'http'

和更多。我的tsconfig.json将typeRoots设置为'./node_modules/@types'，我在本地获得了成功的构建。

为什么Heroku找不到这些类型？
