里面关键的信息就是 "NavigationDuplicated: Avoided redundant navigation to current location: "/"."

出现此类错误主要原因就是因为 $router.push 跳转时,与当前地址相同

解决方法就是在 router 文件夹下的 index.js 中加入下面的代码

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

完整代码就是

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'

Vue.use(VueRouter)

// 解决 NavigationDuplicated: Avoided redundant navigation to current location 报错
const originalPush = VueRouter.prototype.push
VueRouter.prototype.push = function push(location) {
  return originalPush.call(this, location).catch(err => err)
}

const routes = [
  {
