修改router文件夹下index.js
import Vue from 'vue'
import VueRouter from "vue-router";
// 点击左侧菜单栏中的项，重复点击时会报错，解决这个问题
const originalPush = Router.prototype.push
Router.prototype.push = function push(location) {
return originalPush.call(this, location).catch(err => err)
}
Router.prototype.replace = function replace(location) {
return originalPush.call(this, location).catch(err => err)
}
