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

Question

我在Heroku上构建TypeScript应用程序时遇到了困难。

我的依赖项列表包括我正在使用的所有软件包的类型定义：

"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"
  },

但是，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tsconfig.json设置typeRoots为'./node_modules/@types' ，我得到当地一个成功的构建。

为什么Heroku无法找到这些类型？

Answer 1

显然，Heroku并未对我的package.json文件进行更改，或者缓存了构建过程的某些部分，该部分不包括我从devDependencies移到依赖项的@type定义。

我这样清除了构建缓存：

$ heroku plugins:install heroku-repo
$ heroku repo:purge_cache -a [appname]
$ git commit --allow-empty -m "Purge cache"
$ git push heroku master

一切都按预期进行。
