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

报错信息

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

报错原因

将webpack从3升级到5报这个错误

解决过程

直接搜索，需要将启动语法从原来的

"dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",

改成

"dev": "webpack server --config build/webpack.dev.conf.js --progress",

改完之后发现还是报错，但是提示需要安装webpack-cli，然后就安装下

npm install -D webpack-cli

装了之后启动，然后报新的错误

[webpack-cli] You need to install 'webpack-dev-server' for running 'webpack serve'.
Error: Cannot find module 'webpack-dev-server/bin/cli-flags'
Require stack:

看说明需要安装

webpack-dev-server

尝试装下试试，但是安装又报版本的错误

说我目前webpack5没有这个webpack-dev-server这个事webpack2或者3才有的东西，那说明现在启动方式还是不对，不能用这个webpack-dev-serevr启动，仔细发现我本地的package.json里面的不对，版本还是老的，我需要卸载重新安装才行。

然后启动还是报错

Failed to load '/Users/sufubo/code/project/webproject/build/webpack.dev.conf.js' config
[webpack-cli] TypeError: webpack.NamedModulesPlugin is not a constructor

看起来就是webpack语法的问题了，我尝试修改下。
