Option One:
Installation vue-router3.0 the following versions: 3.0 or later uninstall the old version and then install npm install @ vue-router2.8.0 -S

Option II:
for the jump to the same address add routing catch capture at the exception:.. This $ router.push ( ' / location') catch (err => {console.log (err)})

Registration can be a global function in main.js

import Router from 'vue-router'

const originalPush = Router.prototype.push
