我是反应 js 的新手。我正在尝试创建一个组件。为此，我已经安装了成功安装的引导程序（版本 4.1.1）。

然后我在 index.js 中导入了相同的内容，并在重新加载页面 (localhost:3000) 时收到错误消息：

Module not found: 
Can't resolve 'bootstrap/dist/css/bootstrap.css' in 'C:\Users\test\counter-app\src'

我的index.js：

import React from "react";
import ReactDOM from "react-dom";
import "./index.css";
import App from "./App";
import * as serviceWorker from "./serviceWorker";
import "bootstrap/dist/css/bootstrap.css";

ReactDOM.render(<App />, document.getElementById("root"));

serviceWorker.unregister();

我的package.json：

{
  "name": "counter-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.8.4",
