Javascript 网页包-未捕获类型错误：无法读取属性'；呼叫'；未定义的

在我的

vue组件中添加
css样式时，我正在使用
vue.js
获取未捕获的TypeError。
当我在
script
中导入css
或者只是从组件中删除
css样式时，它看起来很好

我对
webpack
配置没有深入的了解。那么，我应该对
webpack.config.js
文件做任何更改吗

我遇到的错误

Vue组件：

<template>
    <div class="section">
        Lorem Ipsum.
    </div>
</template>

<script>
    // Works fine if I import css
    import '_ANYCSS_'

    export default {
        //
    }
</script>

<!--getting TypeError if I add style section-->
<!--I've tried scoped and scss mode, neither works-->
<style>
    .section {
        color: red;
    }
</style>
