关于vue中的样式表引入问题

[已解决问题] 解决于 2017-10-30 16:38

1、用脚手架 搭建基本的 vue 后引入饿了吗框架
import Vue from 'vue'
import Element from 'element-ui'
import 'element-ui/lib/theme-default/index.css'
import App from './App.vue'
Vue.use(Element)
new Vue({
  el: '#app',
  render: h => h(App)
})

2、插入 element-ui 里面的 组件

<el-button type="primary">主要按钮</el-button>
 <el-button type="success">成功按钮</el-button>

3、会报错如下所示到底问题出现在哪了

Cannot find module "element-ui/lib/theme-default/index.css"

这是项目的一些依赖：
