我正在尝试创建一个简单的 vueJs 项目，并在 webpack/babel 的帮助下编译它。但是，在运行npm run dev编译项目并启动 vue 服务器时，我发现 Select.vue 模板的编译失败（安装 vue-strap 时安装的 Select.vue），下面是确切的错误正在我的本地端口上加载：
Failed to compile.

我还附加了我的 main.js 和 App.vue 文件，我在其中调用了 Select.vue 组件：
主.js：
import Vue from 'vue'
import App from './App.vue'
new Vue({
el: '#app',
render: h => h(App)
})
应用程序.vue
<template>
<div>
<app-header></app-header>
<v-select v-model="selected" :options="['Vue.js','React']"></v-select>
<app-footer></app-footer>
</div>
</template>
<script>
import Header from './components/header.vue'
import select from '../node_modules/vue-strap/src/Select.vue'
import Footer from './components/footer.vue'
export default {
components: {
'app-header': Header,
'app-footer': Footer,
'v-select': select,
},
data() {
return {
}
},
}
</script>
<style scoped>
</style>
我想知道为什么我会收到这个错误。我最初在另一个项目中也遇到了这个错误，但是让它过去了，因为我认为这可能是由于我在那里使用的旧版本的依赖项造成的。但是在这个项目中，我使用的是最新的，它仍然没有编译。此外，页眉和页脚工作正常，没有问题。任何帮助表示赞赏。谢谢。
