webpack打包提示: Uncaught Error: Cannot find module 'strip-ansi'

运行webpack-dev-server的时候，可以正常启动服务，但是Terminal控制台报错，如下：

尝试过的方法【无效】

1.重新安装 strip-ansi

yarn add strip-ansi -D

2.删除node_modules目录，重新安装依赖

rm -rf node_modules
yarn install

3.重新安装本地webpack

yarn add webpack -D

以上3种方法均未解决问题

解决问题

仔细排查了一下发现,extensions配置扩展名称的问题（我只写了.ts的问题）

写的不对 没有加.  或者写的不全面

 extensions: ['.js', '.ts', '.json', '.less', '.css']
