vue 2.0 Failed to mount component: template or render function not defined

I am using a Laravel Vue setup and pulling in Laravel Elixir, Webpack and laravel-elixir-vue-2 package.

I have looked at several other SO questions and I know this is usually a problem with not referencing the standalone version of vue.js

However, the laravel-elixir-vue-2 package aliases vue to the standalone version so templates can be loaded from .vue files. Still, I get this error every time:

[Vue:Warn] vue 2.0 Failed to mount component: template or render function not defined. (found in component <top> at ../resources/assets/js/components/top.vue)

I can see that vue.js is being pulled in from vue/dist/vue.js?0598:2611 in the console.

Can anyone see what I'm missing?

app.js

import Vue from 'vue'
import top from './components/top.vue'

new Vue({
el: '#app',
components: { top }
})

//I've also tried this: 

// new Vue({
//  components: {
//    top
//  },
// render: h => h(top),
// }).$mount('#app')

top.vue

<template>
   <div class="top">
     <p>hi</p>
   </div>
</template>
<script>
 export default {};
</script>

index.blade.php

<div>
   <div id="app">
<top></top>
   </div>
</div>
{!! HTML::script('js/app.js') !!}

package.json

{
  "private": true,
  "scripts": {
  "prod": "gulp --production",
  "dev": "gulp watch"
},
"devDependencies": {
   "bootstrap-sass": "^3.3.0",
   "gulp": "^3.9.1",
   "laravel-elixir": "^6.0.0-9",
  "laravel-elixir-vue-2": "^0.2.0",
  "laravel-elixir-webpack-official": "^1.0.2"
  }
 }

gulp.js

var elixir = require('laravel-elixir');
elixir.config.sourcemaps = true;
require('laravel-elixir-vue-2');

elixir(function(mix) {
  mix.webpack('app.js', 'public/assets/js');
});

Edit: update

Changing the gulp.js syntax fixed my error.

var elixir = require('laravel-elixir')
require('laravel-elixir-vue-2')

elixir(mix => {

  mix.webpack('app.js');

  mix.styles([
    "normalize.css",
    "main.css"
    ]);

});

edit: I added export default {}; to the template script

Like my comment in the question, I had the same problem. In my case I had two elixir calls like this:

elixir(mix => {
    mix.browserSync({
        proxy: 'example.dev',
        open: false
    });
});

elixir(mix => {
    mix.sass('app.scss');
    mix.webpack('app.js');
});

I don't know why, but the two elixir calls are breaking webpack. I change my gulpfile to:

elixir(mix => {
    mix.sass('app.scss');
    mix.webpack('app.js');
    mix.browserSync({
        proxy: 'example.dev',
        open: false
    });
});

@retrograde, thx for your hint in your comment :)
