npx webpack-dev-server --open
实行时报错：Cannot find module 'webpack-cli/bin/config-yargs'
结果如下图
问题的缘故原由多数是 webpack 和 webpack-dev-server 之间的版本兼容问题。网友的办理方案也多是逼迫指定特定的版本，如:
"devDependencies": { "webpack": "^5.2.0", "webpack-cli": "^3.3.12", "webpack-dev-server": "^3.11.0"}
觉得此方法很是尴尬，就多滤了几条，在 stackoverflow 上看到这样一句 : You could try changing webpack-dev-server to webpack serve in your npm run script inside package.json. 后面还有一句这样的评论：This is a useful answer particular when your project has these versions webpack": "^5.2.0 webpack-cli": "^4.1.0 webpack-dev-server": "^3.11.0.
于是用下面的命令行试了一下，果真见效：
npx webpack serve --open
后来查看 webpack 5.11 英文版的官方文档中的 Using webpack-dev-server 部分(https://webpack.js.org/guides/development/#using-webpack-dev-server)， 创造它利用的 npm 脚本也是这么利用的：
{ ...... "scripts": { ...... "start": "webpack serve --open" }, ...... }
再看对应的中文翻译，原来是没随着改动过来 .....
