[英]Laravel 5.4 Vue.JS Failed to mount component: template or render function not defined
從 Vue.js 開始，想試試 laravel 自帶的例子。
沒有顯示任何組件，在控制台中我得到
[Vue warn]: Failed to mount component: template or render function not defined.

不是全新安裝，從 5.2->5.3->5.4 升級

require('./bootstrap');
window.Vue = require('vue');
/**

Vue.component('example', require('./components/Example.vue'));
const app = new Vue({
el: '#app'

這是我有 js 的刀片
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Testing</title>
<link rel="stylesheet" href="css/app.css">
<meta name="csrf-token" content="{{ csrf_token() }}">

<body>
<div id="app">

webpack.mix.js
let mix = require('laravel-mix');
mix.js('resources/assets/js/app.js', 'public/js')
.sass('resources/assets/sass/app.scss', 'public/css');
它應該是require('./components/Example.vue').default 。 從 v13 開始， vue-loader將組件導出為默認鍵，在使用import時仍然有效，但在使用require時需要上述內容。
嘗試這個
Vue.component('example-component', require('./components/ExampleComponent.vue').default);
到目前為止，我所擁有的石膏是為所有 Vue 對象的組件添加一個“default()”。
Vue.component('form-component', require('./components/FormComponent').default);
Vue.component('gratitude-pop', require('./components/GratitudePop').default);//..etc..etc
運行這個包：
"devDependencies": {
"axios": "^0.18",
"bootstrap": "^4.0.0",
"cross-env": "^5.1",
"jquery": "^3.2",
"laravel-mix": "^4.0.7",
"lodash": "^4.17.5",
"popper.js": "^1.12",
"resolve-url-loader": "^2.3.1",
"sass": "^1.15.2",
"sass-loader": "^7.1.0",
"vue": "^2.5.17"
},
"dependencies": {
"vuex": "^3.0.1"
}
為使用 VUEX 豎起大拇指；P
這與您安裝 Vue 的方式有關。 一次需要編譯器，另一次不需要https://v2.vuejs.org/v2/guide/installation.html#Runtime-Compiler-vs-Runtime-only 。
你可以試試我的方法（它是純 vue 項目，由 vue webpack 模板制作）：
import Vue from 'vue'
import App from './App'
import Example from './components/Example'
import router from './router' //this will import router/index.js
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
template: '<App/>',
components: { App, Example }
})
這將在全局對象中安裝組件。
我通過在下一行的require().default末尾使用.default方法輕松解決了這個問題。
Vue.component('example-component', require('./components/ExampleComponent.vue').default);
Vue.component('articles', require('./components/ArticleComponent.vue').default);
應用程序.js
/**
* First we will load all of this project's JavaScript dependencies which
* includes Vue and other libraries. It is a great starting point when
* building robust, powerful web applications using Vue and Laravel.
*/
require('./bootstrap');
window.Vue = require('vue');
/**
* Next, we will create a fresh Vue application instance and attach it to
* the page. Then, you may begin adding components to this application
* or customize the JavaScript scaffolding to fit your unique needs.
*/
Vue.component('example-component', require('./components/ExampleComponent.vue'));
Vue.component('articles', require('./components/ArticleComponent.vue').default);
const app = new Vue({
el: '#app',
});
代替
Vue.component('example', require ('./components/Example.vue'));
用這個
Vue.component ('example', require ('./components/Example.vue').default);
將以下行添加到 package.json
"webpack": "cross-env NODE_ENV=development webpack --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"npm 運行 webpack
npm 運行觀察
不要改變任何其他東西
只是在上述答案之上添加一小部分信息。
如果在引發錯誤的組件上添加了.default ，則該錯誤已修復。
