Question

我在前端使用vue js，直到开始使用路由器之前，一切都正常工作，每次使用router-view时，router-view标签消失的组件，我都尝试在我从“应用程序”调用的名为“滑块”的组件，这是我在控制台中看到的错误：

app.js:73366 [Vue warn]: Error in render: "TypeError: Cannot read property 'matched' of undefined"

found in

---> <Slider> at resources/js/components/main/Slider.vue
       <App> at resources/js/views/App.vue
         <Root>

这是app.blade.php

<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">

        <meta charset="utf-8">

    </head>
    <body>
        <div id="app">

    </body>


</html>

App.vue

    <slider></slider>
    <landing></landing>
    <footeralt></footeralt>

Slider.vue

<template>
<div class="container">
    <b-col cols="4" md="4" sm="3" class="float-right">
        <h4 align="left">Quick links</h4>
            <b-list-group style="background-color:transparent" class="text-light">

                    </b-col>
                </div>
            </div>
</template>

app.js

require('./bootstrap');

import Vue from 'vue'
import VueRouter from 'vue-router'
import BootstrapVue from 'bootstrap-vue'
import routes from './routes';


Vue.use(BootstrapVue);


import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'

Vue.config.productionTip = false

window.Vue = require('vue');


/* Main page coponents */
Vue.component('example-component', require('./components/ExampleComponent.vue').default);
Vue.component('navigation', require('./components/main/Navigation.vue').default);
Vue.component('disclaimer', require('./components/main/Disclaimer.vue').default);
Vue.component('slider', require('./components/main/Slider.vue').default);
Vue.component('landing', require('./components/main/Landing.vue').default);
Vue.component('footeralt', require('./components/main/Footer.vue').default);
Vue.component('app', require('./views/App.vue').default);

/* Router */
Vue.use(VueRouter);

const router = new VueRouter({
    mode: 'history',
    routes
});

const app = new Vue({
    el: '#app',
    routes
});

routes.js

import Example from './components/ExampleComponent.vue';
export const routes = [{
    path: '/example',
    component: Example,
    name: 'example'
}];

web.php （Laravel路由）

Route::get('/{any}', 'mainpage\LandingController@index')->where('any', '.*');

LandingController

class LandingController extends Controller
{
    public function index(){
        return view ('app');
    }
}

在您的 app.js 文件中。

// import the App.vue file
import App from "./App.vue";
// import routes this way
import { routes } from "./routes.js";

// rest of the code here

const app = new Vue({
    el: '#app',
    router, // replace routes with router
    render: h => h(App), //indicate the App component inside render function
});

如果上述方法无效，请尝试

// import the App.vue file
import App from "./App.vue";
// import routes this way
import { routes } from "./routes.js";

// rest of the code here

const app = new Vue({
    router, // replace routes with router
    render: h => h(App), //indicate the App component inside render function
}).$mount("#app");

这里的#app是您的id文件中div的{{1}}

index.html构造函数需要Vue对象，而不是router数组

Vue JS + Laravel 6，路由器视图未呈现组件
