VueJS SFC（单个文件组件）无法编译

每当我在SFC〜home.vue中的html中添加额外的html行时，都会出现此错误。看到以下错误：

仅当我在组件的模板标记中的html上添加了额外的html行时，才会发生这种情况。这是组件代码home.vue 

<template>
    <div class="container">
        <div class="banner row align-items-center">
            <div class="col-md-4 col-12">
                <h1 class="banner__header">Earn money on your spare rooms</h1>
                <p class="">Find out how much you could earn.</p>

                <div class="input-group mb-3 banner__calculator">
                    <input type="text" class="form-control" placeholder="Location" list="locations" aria-label="Location">

                    <button type="button" class="btn">GO</button>
                </div>
            </div>
            <div class="col-md-8 col-12 d-none d-sm-block text-center">
                <div class="banner__property">
                    <div class="banner__property__info">
                        <p>NGN 250,000/Year</p>
                        <p>Tayo's Apartment, Yaba, Lagos</p>
                    </div>
                </div>
            </div>
        </div>
    </div>
</template>
<script>
    export default {
        data : function() {
            return { message: 'Hello World' };
        }
    }
</script>

如果我在模板代码中增加了一行，则会收到错误消息。

有人可以解释吗？请记住，我正在使用webpack和vue-loader。

2 个答案:

答案 0 :(得分：5)

在模板的root div之外添加其他任何代码行（html）都是导致此错误的原因。模板只能有一个根元素。

答案 1 :(得分：0)

为来自google的人解答（此答案是此错误的最高结果）。

导致此错误的原因是，我在模板中只有一个根元素，但是没有正确关闭标签（缺少结束标签中的/）。
