无法将 PrimeNG 与 .Net Core 2 Angular 项目模板一起使用

Question

我使用 Visual Studio 2017 15.3 和 Angular Project Template 创建了一个新的 ASP.NET Core 2.0 项目。它工作正常但是当我尝试将 PrimeNG 添加到 packages.json 和 webpack.config.vendor.js 并引用 ButtonModule 我得到以下错误：

NodeInvocationException: Unexpected value 'ButtonModule' imported by the module 'AppModuleShared'. Please add a @NgModule annotation.

有什么想法吗？

app.module.shared.ts:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule } from '@angular/router';

import { NavMenuComponent } from './components/navmenu/navmenu.component';
import { HomeComponent } from './components/home/home.component';
import { FetchDataComponent } from './components/fetchdata/fetchdata.component';
import { CounterComponent } from './components/counter/counter.component';
import { ButtonModule } from 'primeng/primeng';
@NgModule({
    declarations: [
        AppComponent,
        NavMenuComponent,

    ],
    imports: [

        HttpModule,
        FormsModule,
        ButtonModule,
        RouterModule.forRoot([

            { path: 'home', component: HomeComponent },
            { path: 'counter', component: CounterComponent },
            { path: 'fetch-data', component: FetchDataComponent },

Answer 1

如 S_developer 所述，该问题已经。它与 AOT-Compiler 有关，我希望有一天能修复...

Answer 2

将尝试解决方案，因为我也无法让 Prime 工作。已经尝试过 Material 、Dev Express 等。我刚刚用 Material 尝试过，现在可以了。刚刚从索引页面中删除了预呈现，现在它可以工作了。

这只是性能考虑，还是有其他作用。当尝试使用 dev express 控件时，他们声明需要删除该语句。
