vue3的router.index

Vue3 Router的`index`属性通常不是直接使用的，它是在创建`Router`实例时默认设置为`/'`（根路径）。`index`表示当用户访问应用时，如果没有提供特定的路径匹配，路由会自动导航到这个路径。例如：

import { createRouter, createWebHistory } from 'vue-router';
import Home from './views/Home.vue';

const router = createRouter({
  history: createWebHistory(), // 使用浏览器的历史记录管理
  routes: [
    {
      path: '/', // 这就是 index 的值
      component: Home,
      name: 'home',
      meta: { requiresAuth: true }
    },
    // 更多路由...
  ]
});

当你需要配置默认路由页面时，可以修改`index`，但通常我们更倾向于通过`path`选项来定义。同时，`router.push('/')`、`this.$router.go(0)`这样的操作也可以达到类似的效果，即导航到应用的主页。

这个报错是因为在使用Vue Router时，导入的Vue Router版本与当前项目中的Vue版本不匹配导致的。具体来说，Vue Router中使用了Vue 3的语法而当前项目中使用的是Vue 2，所以会出现一些语法上的错误。解决方法是将Vue Router更新到与当前项目中使用的Vue版本相匹配的版本。

vue使用this.$router.push的时候出现了this.$router.push is not a function，为什么？

根据提供的引用内容，出现“this.$router.push is not a function”错误的原因可能是因为在Vue项目的index.js文件中重写了Router.prototype.push方法，导致this.$router.push方法失效。解决方法是在重写的push方法中返回原始的push方法，如下所示：

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

这样就可以解决this.$router.push is not a function的问题了。
