Vue 延迟加载组件

Question

我想尝试在我的自定义 vue 应用程序中延迟加载一个模块，但我遇到了一个问题。

基本上，我从数据库中设置了我的路线，其中之一是显示程序的路线（针对儿童）。 在这个程序中，我加载了几个组件，如客户列表、同意书等。

目前，我有这样的：

   <div role="tabpanel" class="tab-pane" :class="{'active': current_tab == 'consent'}" id="consent" v-if="displayConsentComponent">
    <consent v-model="consents" :edit="edit"></consent>
</div>

// and they are imported like so:

<script>
    import Consent                  from './_consents';
    import AssignedStaff            from './_assigned-staff';
        ......
    export default {
        components:{
            Consent,
            AssignedStaff,
            .....
        },
        data(){
            return {
                  ..........
            }
        }
    }
</script>

但想像你一样适应它，所以我把它改成了这样：

<div role="tabpanel" class="tab-pane" :class="{'active': current_tab == 'consent'}" id="consent" v-if="displayConsentComponent">
    <consent v-model="consents" :edit="edit"></consent>
</div>

// and they are imported like so:

<script>
    const Consent       = () => import('./_consents');
    const AssignedStaff = () => import('./_assigned-staff');
        ......
    export default {
        components:{
            Consent,
            AssignedStaff,
            .....
        },
        data(){
            return {
                  ..........
            }
        }
    }
</script>

但不幸的是，我的整个应用程序无法构建和运行（如果我重建它），否则会出现此错误：

in ./~/babel-loader/lib!./~/vue-loader/lib/selector.js?type=script&index=0!./src/components/programs/program.vue Module parse failed: E:\Gabi\khcc-crm-playground\node_modules\babel-loader\lib\index.js!E:\Gabi\khcc-crm-playground\node_modules\vue-loader\lib\selector.js?type=script&index=0!E:\Gabi\khcc-crm-playground\src\components\programs\program.vue

我已经更新了我的节点包，包括 vue 到最新版本（2.5.1X，如果我没记错的话），但无济于事。 有人可以帮我想想吗？

非常感谢，加布里埃尔

也许您需要将 async 组件移动到components 。 您可以访问此处了解更多信息： https ://v2.vuejs.org/v2/guide/components-dynamic-async.html#Async-Components

<script>

    export default {
        components:{
            Consent: () => import('./_consents'),
            AssignedStaff: () => import('./_assigned-staff'),
            .....
        },
        data(){
            return {
                  ..........
            }
        }
    }
</script>
