参考博客https://www.cnblogs.com/xinheng/p/13019818.html

可以在router的配置文件中（router -> index.js）加上下面这句话，注意位置：

// 解决ElementUI导航栏中的vue-router在3.0版本以上重复点菜单报错问题
const originalPush = VueRouter.prototype.push
VueRouter.prototype.push = function push(location) {
  return originalPush.call(this, location).catch(err => err)
}
