1、安装ElementUI
2、在main.js文件中加入
3、使用组件
终端运行：
Element，一套为开发者、设计师和产品经理准备的基于Vue2.0的桌面端组件库.
1、安装ElementUI
控制台输入
npm i element-ui -S
2、在main.js文件中加入
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';Vue.use(ElementUI);
导入ElementUI
import Vue from 'vue'
import App from './App.vue'
//导入elementUI
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);
Vue.config.productionTip=false
import router from './router/index.js'
Vue.use(router);
new Vue({
el: '#app',
router,
render: h => h(App)
}).$mount('#app')
3、使用组件
创建src下目录的router
index.js
import Vue from "vue";
// 导入路由
import router from "vue-router";
//导入注册组件
import Index from '../Index.vue';
import Login from '../Login.vue';
import MajorList from"../views/MajorList.vue";
import StudentList from"../views/StudentList.vue";
/* 注册 定义组件访问地址 */
Vue.use(router);
var rout = new router({
routes: [{
path: '/',
component: Login
},
{
path: '/login',
component: Login
},
{
path: '/index',
component: Index,
children: [{
path: '/majorlist',
component: MajorList
},
{
path:'/studentlist',
component: StudentList
}
]
}
]
});
//导出路由对象
export default rout;创建src下目录的views
