npm run dev报错This dependency was not found

Question

部署了一套vuecli2.0 运行正常，因为要用路由懒加载，卸载了babel6所有依赖，安装了babel7所有依赖，重新运行npm run dev，结果报错：

This dependency was not found:

* E:\个人资料\项目\net_new_hosback_4.0database\web_vue2.0\node_modules\webpack-dev-server\client\index.js?http://localhost:8080 in multi (webpack)-dev-server/client?http://localhost:8080 webpack/hot/dev-server ./src/main.js

To install it, you can run: npm install --save E:\个人资料\项目\net_new_hosback_4.0database\web_vue2.0\node_modules\webpack-dev-server\client\index.js?http://localhost:8080

This relative module was not found:

* ./src/main.js in multi (webpack)-dev-server/client?http://localhost:8080 webpack/hot/dev-server ./src/main.js
求大神们帮忙找下问题
