输入指令npx webpack-dev-server报错：Error: Cannot find module ‘webpack-cli/bin/config-yargs‘的解决方法

输入指令：npx webpack-dev-server显示如下报错信息：

  throw err;

}

原因：webpack现在存在一个bug,最新版的webpack-dev-server 和最新版的webpack-cli 并不兼容。
解决办法：
打开package.json，查看依赖包的版本：

{
  "name": "test",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "dependencies": {},
  "devDependencies": {
    "css-loader": "^5.0.1",
    "html-webpack-plugin": "^4.5.1",
    "style-loader": "^2.0.0",
    "webpack": "^5.16.0",
    "webpack-cli": "^4.4.0",
    "webpack-dev-server": "^3.11.2"
  }
}

重新下载webpack-cli正确的版本。（“webpack-cli”: “^3.3.12”,和
“webpack-dev-server”: "^3.11.2"是互相兼容的，报错之前的版本是webpack-cli 4.4.0）

如果你找不到与webpack-dev-server兼容的webpack-cli版本号，可以去node_modules中的webpack-dev-server/bin/webpack-dev-server.js代码中寻找webpack-dev-server依赖webpack-cli的版本号。
