报错：
Uncaught (in promise) NavigationDuplicated: Avoided redundant navigation to current location

解决办法：
在路由文件中加入如下代码，即可解决

import VueRouter from "vue-router";

//push
const VueRouterPush = VueRouter.prototype.push
VueRouter.prototype.push = function push (to) {
    return VueRouterPush.call(this, to).catch(err => err)
}

//replace
const VueRouterReplace = VueRouter.prototype.replace
VueRouter.prototype.replace = function replace (to) {
  return VueRouterReplace.call(this, to).catch(err => err)
}
