左侧菜单栏时，发现点击路由跳转相同地址 会有这个报错
Uncaught (in promise) NavigationDuplicated {_name: "NavigationDuplicated", name: "NavigationDuplicated"}
router.js(或者router文件夹下index.js)中，添加这段代码
import Router from 'vue-router'; Vue.use(Router) // 添加这下面一段代码，就可以解决报错 const originalPush = Router.prototype.push;
Router.prototype.push = function push(location) {
return originalPush.call(this, location).catch(err => err)
};
