《前端》webpack报错：npm ERR! vue-admin-template@4.4.0 dev: `vue-cli-service serve`

解决方案

1.删除node_model文件夹

2.终端执行npm install.慢的话可以执行淘宝镜像

npm install cnpm -g --registry=https://registry.npm.taobao.org

npm uninstall webpack-dev-server
 
npm install webpack-dev-server@2.9.1
 
npm run dev

 设置淘宝镜像

npm config set registry https://registry.npm.taobao.org
