使用vue-select时编译失败

Question

我正在尝试创建一个简单的vueJs项目，并在webpack / babel的帮助下进行编译。但是，在运行npm run dev来编译项目并启动vue服务器时，我得到Select.vue模板的编译失败（安装vue-strap时已安装的Select.vue），如下所示在我的本地端口上加载的确切错误：

Failed to compile.

 @ ./node_modules/vue-strap/src/Select.vue 11:0-220
 @ ./node_modules/babel-loader/lib!./node_modules/vue-loader/lib/selector.js?type=script&index=0!./src/App.vue
 @ ./src/App.vue
 @ ./src/main.js
 @ multi (webpack)-dev-server/client?http://localhost:8080 webpack/hot/dev-server ./src/main.js

我还将附加我的main.js和App.vue文件，在其中调用Select.vue组件：

main.js：

import Vue from 'vue'
import App from './App.vue'

new Vue({
  el: '#app',
  render: h => h(App)
})

App.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此错误。我最初在另一个项目中也遇到了此错误，但请放开它，因为我认为这可能是由于我在那里使用过旧版本的依赖项所致。但是在这个项目中，我使用的是最新版本，但仍未编译。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。

Answer 1

这些错误解释了它：

- name="{{name}}": Interpolation inside attributes has been removed. Use v-bind or the colon shorthand instead. For example, instead of <div id="{{ val }}">, use <div :id="val">.
- placeholder="{{searchText||text.search}}": Interpolation inside attributes has been removed. Use v-bind or the colon shorthand instead. For example, instead of <div id="{{ val }}">, use <div :id="val">.
- invalid expression: Unexpected identifier in

  options | filterBy searchValue

Raw expression: v-for="option in options | filterBy searchValue"

1）将name="{{name}}"替换为:name="name"

2）将placeholder="{{searchText||text.search}}"替换为:placeholder="searchText || text.search"

3）不推荐使用filterBy-try replacing what you're iterating over with a computed method
