Add the following code to the index.js file under the router folder:

import Router from 'vue-router'

// Solve the problem that vue-router in the navigation bar of ElementUI reports an error when repeatedly clicking the menu in version 3.0 or above

const originalPush = Router.prototype.push
Router.prototype.push = function push(location) {
  return originalPush.call(this, location).catch(err => err)
}
