解决方案1：

捕获异常

this.$router.push('/home').catch(err => console.log(err))

也可以不打印错误信息

this.$router.push('/home').catch(err => {})

解决方案2：

在跳转时，判断路由和当前路由是否一致，如果不一致再跳转
注意：this.$route.path可以获取到当前的路由路径（不是$.router）

  if (this.$route.path != '/home') {
    this.$router.push('/home')
  }

解决方案3：

在src–>router–>index.js添加代码：

const router = new VueRouter({
    routes,
    mode: 'history',
    // 修改linkActiveClass
    linkActiveClass: 'active'

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