我一直在尝试为我的NextJS项目使用Typescript...我以为开始使用Typescript会是最困难的，但事实并非如此：其安装甚至更加复杂。
我遵循了official documentation上的说明（创建一个新项目）。
以下是我所做的：

npx create-next-app --ts
cd test-nextts
npm run dev

下面是我在npm run dev上遇到的错误：

> test-nextts@0.1.0 dev
> next dev

ready - started server on 0.0.0.0:3000, url: http://localhost:3000
It looks like you're trying to use TypeScript but do not have the required package(s) installed.

Please install @types/react by running:

        npm install --save-dev @types/react

If you are not trying to use TypeScript, please remove the tsconfig.json file from your package root (and any TypeScript files in your pages directory).

它说我没有安装“所需的软件包”，而我安装了。下面是在npx create-next-app --ts之后自动生成的package.json：

{
  "name": "test-nextts",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"
  },
  "dependencies": {
    "next": "12.1.4",
    "react": "18.0.0",
    "react-dom": "18.0.0"
  },
  "devDependencies": {
    "@types/node": "17.0.23",
    "@types/react": "18.0.2", // <--- HERE IT IS
    "@types/react-dom": "18.0.0",
    "eslint": "8.13.0",
    "eslint-config-next": "12.1.4",
    "typescript": "4.6.3"
  }
}

它要求我运行npm install --save-dev @types/react（即使我不应该这样做）。

因此，我尝试了另一个npm run dev，问题是：它一遍又一遍地打印完全相同的错误！为什么？
如果我尝试修改现有的Javascript项目，也会出现同样的错误。
拜托，帮帮我。
