我在Visual Studio 2017(版本15.3.2)中使用Angular模板创建了新的Asp.net核心Web应用程序项目。
然后我安装ngx-facebook

将FacebookModule导入应用程序的根模块
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 { AppComponent } from './components/app/app.component';
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 { FacebookModule } from 'ngx-facebook';
@NgModule({
declarations: [
AppComponent,
NavMenuComponent,
CounterComponent,
FetchDataComponent,
HomeComponent
],
imports: [
CommonModule,
HttpModule,
FormsModule,
FacebookModule.forRoot(),
RouterModule.forRoot([
{ path: '', redirectTo: 'home', pathMatch: 'full' },
{ path: 'home', component: HomeComponent },
{ path: 'counter', component: CounterComponent },
{ path: 'fetch-data', component: FetchDataComponent },
{ path: '**', redirectTo: 'home' }
])
]
})
export class AppModuleShared {
}
尝试注入FacebookService
import { Component } from '@angular/core';
import { FacebookService } from 'ngx-facebook';
@Component({
selector: 'app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
}
当我运行项目时,发生错误:NodeInvocationException:由于错误导致预渲染失败:错误:找不到模块"。" http://take.ms/ImVYb

我做错了什么?感谢。
答案 0 :(得分:0)
我在visual studio 2017中运行时遇到了同样的问题。它在&#39; ./ components / home / home.component&#39;中丢失了一个文件夹。 =&GT; &#39; ./组件/ fetchdata /家/ home.component&#39 ;.
希望这有帮助。
