#1.在项目开发目录使用脚手架新建vue项目（需要提前安装好node和webpack）
vue init webpack element_user(项目名)
#2.进入当前构建好的vue项目下，下载elementui依赖
cd element_user
npm i element-ui -S
#3.进入项目src目录下的main.js文件加入配置
# 相当于将elementui所有样式和组件引入
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
#将elementui全局组件注册到实例上
Vue.use(ElementUI);
