使用vue-select时编译失败

Question

我试图创建一个简单的vueJs项目，并在webpack/babel的帮助下编写它。但是，在运行npm来编译项目并启动vue服务器时，我会看到Select.vue模板的编译失败(安装vue-strap时安装的Select.vue )，下面是在我的本地端口上加载的确切错误：

Failed to compile.

  - 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">.

    options | filterBy searchValue

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


 @ ./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

我还附加了我的main.js和App.vue文件，我在其中调用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犯这个错误。最初，我在另一个项目中也出现了这个错误，但是让它去吧，因为我认为这可能是由于我在那里使用的依赖关系的旧版本造成的。但在这个项目中，我使用的是最新的，但它仍然没有编译。此外，页眉和页脚工作正常，在它们中没有问题。任何帮助都是非常感谢的。谢谢。

Answer 1

这些错误解释了这一点：

- 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. filterBy被废弃了- 尝试用计算方法替换正在迭代的内容

Answer 2

根据您所说的内容和错误中显示的代码，您正在使用以下库：https://github.com/yuche/vue-strap

这个库不再使用，更重要的是，它与您使用的Vue 2.9不兼容。

您可以尝试使用与Vue 2兼容的这个备用叉子，但请记住，您可能需要更改代码库。
