Der folgende Fehler wird beim Ausführen von gulp gemeldet:

[07:11:05] gulp-notify: [Laravel Elixir] Browserify Failed!: Parsing file /home/vagrant/Code/TaskManager/resources/assets/js/vue/components/stepList.vue: 'import' and 'export' may appear only with 'sourceType: module' (22:0)

.vue-Dateicode lautet wie folgt:

<template>
    <li class="list-group-item">
        <span @dblclick="editStep(step)">{{ step.name }}</span>
        <span class="pull-right">
            <i class="fa fa-check " @click="toggleCompletion(step)"></i>
            <i class="fa fa-close " @click="removeStep(step)"></i>
        </span>
    </li>
</template>

<script>
    export default {
        props:['step']
    }
</script>

<style>
</style>

Entschuldigung, was ist los?
