Webpack wepack4 vuejs ssr es5:（0，_app.createApp）不是函数

回购金： 布兰奇： （sass）

我尝试在sass加载程序的IncludePath中更新vue加载程序以提取sass 对于webpack:但当我编译时获得此错误：

TypeError:（0，_app.createApp）不是函数 在es5_server_entry.js:441:39 在新的承诺（） 在module.exports../src/entry-server.js.exports.default（src/entry-server.js:4:8）处 at/Users/vincent/Desktop/SSR-vue-template/node_-modules/vue-server-renderer/build.js:8375:43 在新的承诺（） at/Users/vincent/Desktop/SSR vue template/node_modules/vue server renderer/build.js:8372:14 在Object.renderString（/Users/vincent/Desktop/SSR vue template/node_modules/vue server renderer/build.js:8564:9） 在app.get（/Users/vincent/Desktop/SSR-vue-template/server.js:64:11） 在Layer.handle[作为handle_请求]（/Users/vincent/Desktop/SSR vue template/node_modules/express/lib/router/Layer.js:95:5） 接下来（/Users/vincent/Desktop/SSR-vue-template/node_-modules/express/lib/router/route.js:137:13）

my entry server仅导入my app.js：

import { createApp } from './app'

export default context => {
    return new Promise(
        (resolve, reject) => {
            const { app, router, store } = createApp()

            router.push(context.url)

            router.onError((err) => {
                console.log(err)
            })

            router.onReady(() => { 

                const matchedComponents = router.getMatchedComponents()

                if(!matchedComponents.length){
                    return reject({ code: 404})
                }

                Promise.all(matchedComponents.map(
                    component => {
                        if(component.asyncData) {
                            return component.asyncData({
                                store, 
                                route: router.currentRoute
                            })
                        }
                    }
                )).then(() => {
                    context.state = store.state
                    resolve(app)
                }).catch(reject)

            }, (reject) => { console.log(reject)})
        }
    )
}

还有我的app.js：

import Vue from 'vue'
import App from './App.vue'
import { createRouter } from './router'
import { createStore } from './store'
import { sync } from 'vuex-router-sync'
import metaMixin from './Utils/meta-mixin'
import filters from './Utils/filters'

Vue.mixin(metaMixin)
Vue.use(filters)


export function createApp () {
    const router = createRouter()
    const store = createStore()

    // synchroniser pour que l'état de la route soit disponible en tant que donnée du store
    sync(store, router)

    const app = new Vue({
        router,
        store,
        render: h => h(App)
    })

    return { app, router, store }
}

问题在哪里，我不明白，我会发疯的

网页生成的代码：

                }
            })).then(function () {
                context.state = store.state;
                resolve(app);
            }).catch(reject);
        }, function (reject) {
            console.log(reject);
        });
    });
};

似乎网页包搜索app.view而不是app.js
