vueRouter:Avoided redundant navigation to current location

1、问题描述：

最近使用ElementUI的NavMenu 导航菜单组件的时候，发现一个导航被重复点击的时候，

element-ui.common.js?b705:3354 Error: Avoided redundant navigation to current location: "/management/arrange".

2、解决方案，在router文件目录index.js添加下面代码

// 解决ElementUI导航栏中的vue-router在3.0版本以上重复点菜单报错问题
const originalPush = VueRouter.prototype.push
VueRouter.prototype.push = function push(location) {
  return originalPush.call(this, location).catch(err => err)
}
