找不到名称“要求”。 （反应 + 打字稿）

Question

我收到此错误：找不到名称“require”。您需要为节点安装类型定义吗？试试npm i @types/node。

问题出在 server.ts 上，这是我第一次使用 Typescript 创建服务器文件，所以我没有太多知识

但是 Types/node 已经在 package.json 中了：

{
  "name": "client",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@carbon/icons-react": "^10.10.2",
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.3.2",
    "@testing-library/user-event": "^7.1.2",

    "typescript": "~3.7.2"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "@types/node": "^13.13.5",
    "@types/react": "^16.9.34"
  }
}

server.ts:

const path = require('path');
const express = require('express');
const cors = require('cors');
const bodyParser = require('body-parser');
const fallback = require('express-history-api-fallback');

const app = express();

在打字稿中，您应该使用import 语法而不是require 来包含模块。例如：

import path from 'path';
import express from 'express';
