Vue页面中引入img图片的方法
我们在学习html的时候，图片标签<img>引入图片
1
<img src="../assets/images/avatar.png" width="100%">但是这样会有2个弊端：
因为采用绝对路径引入，所以如果后面这张图片移动了目录，就需要修改代src里的路径
如果这张图片在同一页面内有多个地方要使用到，就需要引入多次，而且图片移动了目录，这么多地方都要修改src路径
怎么办？使用动态路径import、require
首先讲讲这两个兄弟，在ES6之前，JS一直没有自己的模块语法，为了解决这种尴尬就有了require.js，在ES6发布之后JS又引入了import的概念
使用import引入
import之后需要在data中注册一下，否则显示不了
