热重载不适用于我的 webpack 5 反应项目

我正在创建一个新项目。当我完成安装 npm 包并运行基本设置时，一切正常，除了当我在代码中进行更改并保存文件并移动到浏览器以查看更改时，页面没有在浏览器中重新加载。我必须手动刷新页面才能看到新的更改。

这是我的 package.json 文件：

{
  "name": "resume",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack serve"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "@babel/preset-react": "^7.12.10",
    "react": "^17.0.1",
    "react-dom": "^17.0.1"
  },
  "devDependencies": {
    "@babel/core": "^7.12.10",
    "@babel/plugin-proposal-class-properties": "^7.12.1",
    "@babel/preset-env": "^7.12.11",
    "babel-loader": "^8.2.2",
    "clean-webpack-plugin": "^3.0.0",
    "html-webpack-plugin": "^4.5.1",
    "webpack": "^5.12.2",
    "webpack-cli": "^4.3.1",
    "webpack-dev-server": "^3.11.1"
  }
}

这是我的 webpack.config.js：

const path = require('path')
const webpack = require('webpack')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const { CleanWebpackPlugin } = require('clean-webpack-plugin')
const { web } = require('webpack')

module.exports = {
    mode: 'development',
    devServer: {
        historyApiFallback: true,
        contentBase: path.resolve(__dirname, './dist'),
        open: true,
        compress: true,
        hot: true,
        port: 8080,
    },
    target: 'web',
    // entry: {
    //     main: path.resolve(__dirname, './src/index.js'),
    // },
    // output: {
    //     path: path.resolve(__dirname, './dist'),
    //     filename: '[name].bundle.js',
    // },
    module: {
        rules: [
            // JavaScript
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: ['babel-loader'],
            },
        ],
    },
    plugins: [
        new HtmlWebpackPlugin({
            title: 'webpack Boilerplate',
            template: path.resolve('./index.html'),
            filename: 'index.html', // output file
        }),
        new CleanWebpackPlugin(),
        new webpack.HotModuleReplacementPlugin(),
    ],
}

我在网上搜索了一下，问题似乎出在webpack-开发服务器，但我不确定。请帮忙。

Update webpack-开发服务器版本为4.0.0-beta.0我也有同样的问题。
