导入vue.js组件

Question

我正在尝试将Vuelidate插件库导入到newsletter.vue.js组件中。

但是此导入返回错误：Uncaught SyntaxError：意外的标识符

如何将其导入到vue.js组件中？

首先，我正在使用webpack并首先致电Vuelidate：

/**
 * First we will load all of this project's JavaScript dependencies which
 * includes Vue and other libraries. It is a great starting point when
 * building robust, powerful web applications using Vue and Laravel.
 */

require('./bootstrap');


window.Vue = require('vue');

import BootstrapVue from 'bootstrap-vue'
import Vuelidate from 'vuelidate'

Vue.use(BootstrapVue)
Vue.use(Vuelidate)

/**
 * The following block of code may be used to automatically register your
 * Vue components. It will recursively scan this directory for the Vue
 * components and automatically register them with their "basename".
 *
 * Eg. ./components/ExampleComponent.vue -> <example-component></example-component>
 */

// const files = require.context('./', true, /\.vue$/i)
// files.keys().map(key => Vue.component(key.split('/').pop().split('.')[0], files(key).default))

//Vue.component('example-component', require('./components/ExampleComponent.vue').default);

/**
 * Next, we will create a fresh Vue application instance and attach it to
 * the page. Then, you may begin adding components to this application
 * or customize the JavaScript scaffolding to fit your unique needs.
 */

const app = new Vue({
});

window.onload = function(){
    app.$mount('#app');
}

然后，我看到必须将“ vuelidate / lib / validators”导入组件才能使用它。

像这个例子。

问题是我无法在组件Vue内进行导入，它总是给我错误。

这是我组件的代码：

import validators from 'vuelidate/lib/validators';//this return me error

Vue.component('newsletter', {

    template :  '<div>\
      <b-form @submit="onSubmit">\
        \
          \
        <b-form-group id="exampleInputGroup2" label="Food" label-for="exampleInput2">\
          <b-form-select\
            id="exampleInput2"\
            :options="foods"\
            :state="$v.form.food.$dirty ? !$v.name.$error : null"\
            v-model="form.food"\
          />\
  \
          <b-form-invalid-feedback id="input2LiveFeedback">\
            This is a required field\
          </b-form-invalid-feedback>\
        </b-form-group>\
  \
        <b-button type="submit" variant="primary" :disabled="$v.form.$invalid">Submit</b-button>\
      </b-form>\
    </div>',

    props : ['route_post'],

    data: function()
    {
        return {
            foods: ['apple', 'orange'],
            form: {}
          }
    },  

    validations: {
      form: {
        name: {
          required: validators.required,
          minLength: validators.minLength(3)
        }
      }
    },

});

您首先必须将其添加到您的应用程序中，如下所示：

import Vue from 'vue'
import Vuelidate from 'vuelidate'
Vue.use(Vuelidate)

然后，您可以通过解构来使用它，如下所示：

import { validators } from 'vuelidate'
