webpack5: Error: Cannot find module ‘webpack-cli/bin/config-yargs‘

webpack5X版本报错：

Error: Cannot find module 'webpack-cli/bin/config-yargs'

错误原因：

wbepack4X版本使用webpack-dev-server，启动方式为：webpack-dev-server。webpack5X修改为：webpack server

webpack4X方式：

webpack-dev-server --mode development --config config/webpack.conf.js

webpack5X方式：

webpack serve --mode development --env development --config config/webpack.conf.js

参考：github webpack-dev-server issues
