vue如何清除router

要定义vue-router的动态路由可以使用$route.params对象来接收动态参数，可以在定义路由时使用冒号来定义动态部分。例如：

const router = new VueRouter({
  routes: [
    {
      path: '/user/:userId',
      name: 'user',
      component: User
    }
  ]
})

在上述示例中，我们定义了一个名为'user'的路由，路径为'/user/:userId'，其中':userId'表示这部分是动态路由参数。在组件中可以按照以下方式访问这个参数：

this.$route.params.userId

这样就可以获取动态路由参数的值。

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。

在Vue3.0中，下列Vue-router插件的安装命令正确的是__________。 A npm i vue-router@next B node install vue-router C npm Install vueRouter D npm I vue-router

正确的安装命令是 A) `npm i vue-router@next`，它会安装 Vue3.0 版本的 Vue-router。B) `node install vue-router` 是错误的，正确的是使用 npm 来安装。C) `npm Install vueRouter` 大小写不正确，应该是小写的 `npm install`。D) `npm I vue-router` 大小写不正确，应该是小写的 `npm i`。
