Typescript无法解析react-router-dom

Question

我正在尝试使用Typescript React应用程序中的React Router。在运行yarn create react-app my-app --template typescript之后，按照在create-react-app docs中的说明并安装@types/react-router-dom，我的package.json如下所示：

{
  "name": "allpic-frontend",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.11.4",
    "@testing-library/react": "^11.1.0",
    "@testing-library/user-event": "^12.1.10",
    "@types/jest": "^26.0.15",
    "@types/node": "^12.0.0",
    "@types/react": "^16.9.53",
    "@types/react-dom": "^16.9.8",
    "@types/react-router-dom": "^5.1.6",
    "react": "^17.0.1",
    "react-dom": "^17.0.1",
    "react-scripts": "4.0.1",
    "typescript": "^4.0.3",
    "web-vitals": "^0.2.4"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我的App.tsx包含以下内容：

import React from 'react';
import './App.css';
import {BrowserRouter as Router, Link, Route, Switch} from "react-router-dom";

function App() {
  return (
    <Router>
      <Link to="/">
        <h1>Home</h1>
      </Link>
      <Link to="/upload">
        <h1>Upload</h1>
      </Link>
      <Switch>
        <Route path="/">
          <h1>hello world</h1>
        </Route>
      </Switch>
    </Router>
  );
}

export default App;

在运行yarn start时，我得到了以下错误：

Module not found: Can't resolve 'react-router-dom' in '/home/max/Projects/allpic/allpic-frontend/src'
/home/max/Projects/allpic/allpic-frontend/node_modules/react-scripts/scripts/start.js:19
  throw err;
  ^

[Error: ENOENT: no such file or directory, stat '/home/max/.face.icon'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'stat',
  path: '/home/max/.face.icon'
}
error Command failed with exit code 1.

正如我所说的，这是一个新鲜的项目。除了上面提到的以外，我没有做任何事情。我试图通过在start.js:19上放置一个断点来调试这个问题，但是我没有从侦听器获得任何堆栈跟踪。

我如何克服这个问题，使我的Typescript应用程序编译并与React Router一起工作？

请同时安装实际的react-router-dom库。

yarn add react-router-dom
