package.json

  {
  "name": "test5",
  "version": "1.0.0",
  "description": "",
  "main": "webpack.config.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",

}

webpack.config.js

const {resolve} = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
    entry: './src/index.js',
    output: {
        filename: 'built.js',
        path: resolve(__dirname, 'build')
    },
    module: {
        rules: [
            {
                test: /\.css$/,
                use: ['style-loader', 'css-loader']
            },
            {
                exclude: /\.(js|html|css)$/,
                loader: 'file-loader',
            }
        ]
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: './src/webpack.html'
        })
    ],
    mode: 'development',

    //devServer
    devServer: {
        contentBase: resolve(__dirname, 'build'),
        compress: true,
        port: 3000,
        open: true
    }

};

问题：

当我执行npx webpack-dev-server

2.ErrorMessage：

    Error: Cannot find module 'webpack-cli/bin/config/config-yargs'
    Require stack:
    - D:\webpack workspace\test5\node_modules\webpack-dev-server\bin\webpack-dev-server.js

at Object.<anonymous> (D:\webpack workspace\test5\node_modules\webpack-dev-server\bin\webpack-dev-server.js:65:1)

      code: 'MODULE_NOT_FOUND',
      requireStack: [
        'D:\\webpack workspace\\test5\\node_modules\\webpack-dev-server\\bin\\webpack-dev-server.js'
      ]

webpack-dev-server.js

// webpack-cli@3.3 path : 'webpack-cli/bin/config/config-yargs'
let configYargsPath;
try {
  require.resolve('webpack-cli/bin/config/config-yargs');
  configYargsPath = 'webpack-cli/bin/config/config-yargs';
} catch (e) {
  configYargsPath = 'webpack-cli/bin/config-yargs';
}
// eslint-disable-next-line import/no-extraneous-dependencies
// eslint-disable-next-line import/no-dynamic-require
require(configYargsPath)(yargs);

// It is important that this is done after the webpack yargs config,
// so it overrides webpack's version info.
yargs.version(getVersions());
yargs.options(options);

const argv = yargs.argv;

那么，该如何处理呢？我花了很多时间来做这个bug，但这不好。

（而且，package.json上的这些npm文件是最新的。）

请给我一些有效的提示。非常感谢

已解决：

        I have already solved this problem,
        we can use `webpack serve` to run `webpack-dev-server`
        so we just change the package.json file
    
        1."start-dev":"webpack-dev-server"
        to the
        "dev":"webpack serve"

     the final step is npm run dev;okay!successful!

2.First time we use npx webpack-dev-server
but now we just write npx webpack serve in terminal
okay!successful

执行npx webpack-dev-server，找不到模块
