导入 Vue 组件

Question

我有一个注册的 Vue 组件：

Vue.component('logo', function (resolve) {require(['./components/layout/Logo.vue'], resolve)});

组件本身定义为：

<template>
    <div>
        <div class="title">
            <a href="/">
                <h1>Welcome to my Site!</h1>
            </a>
        </div>
        <navigation></navigation>
    </div>
</template>

<style scoped>
    h1 {
        text-decoration: underline;
        text-align: center;
        color: #000000;
    }

</style>

<script>
    import Navigation from './Navigation.vue';

    export default {
        data() {
            return {
                msg:'hello vue'
            }
        },
        components: {
            Navigation
        }
    }

</script>

Logo.vue 和 Navigation.vue 在同一目录中。 Webpack 运行时不会报错。

当网站加载但报告控制台错误时：

app.js:142 TypeError: Cannot read property 'call' of undefined
    at __webpack_require__ (app.js:50)
    at app.js:883

当我用Vue.component('navigation', function (resolve) {require(['./components/layout/Navigation.vue'], resolve)});全局注册第二个组件时，无论我是否使用该组件，都会出现同样的错误。

我的webpack.mix.js 包含：

mix.webpackConfig({
    output: {
        filename: "js/[id].js"
    }
});

删除它后，我能够正确加载。这是为了将输出的块文件移动到js/目录，但显然是错误的。
