vue-router——message: "Navigating to current location (XXX) is not allowed"

解決方法：

• 法一：重寫規則

import VueRouter from "vue-router";

const [routerPush, routerReplace] = [VueRouter.prototype.push, VueRouter.prototype.replace];
VueRouter.prototype.push = function push(location) {
  return routerPush.call(this, location).catch(error => error);
};
VueRouter.prototype.replace = function replace(location) {
  return routerReplace.call(this, location).catch(error => error);
};

• 法二：降級處理（3.1 以下）
