在Vue中使用外部模板文件进行单元测试

我正在使用带有webpack模板的vue-cli，当我将模板文件拆分到不同的文件中，并运行 npm run unit 或 yarn run unit 时，我收到此错误：

$ yarn run unit

./src/components/Hello.pug中的警告模块解析失败：/home/jmanuelrosa/Developer/test-vue/src/components/Hello.pug意外的令牌（1：0）您可能需要一个合适的加载器来处理这个问题文件类型 . | .hello | h1 {} | h2 Essential Links @ ./src ^ . /（?! main（.js）？$）@ ./test/unit/index.js

我尝试使用基本的Hello示例，我得到了同样的错误 . 这是我的组件与帕格模板（我也安装了哈巴狗）：

<template lang='pug' src='./Hello.pug'></template>

<script>
export default {
  name: 'hello',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
h1, h2 {
  font-weight: normal;
}

ul {
  list-style-type: none;
  padding: 0;
}

li {
  display: inline-block;
  margin: 0 10px;
}

a {
  color: #42b983;
}
</style>

和帕格模板：

.hello
  h1 {{ msg }}
  h2 Essential Links
  ul
    li
      a(href='https://vuejs.org', target='_blank') Core Docs
    li

    li

这个问题与＃531有关

在本期中，用户说解决方案是更改扩展，并使用tpp.html，但是，与dev或环境有什么区别？我需要为业力安装另一个插件吗？

谢谢 ！
