Question

错误我收到了：

无法绑定到＆＃39; ngforOf＆＃39;因为它不是“div”的已知属性。（＆＃34;] * ngfor =＆＃34;让项目[1,2,3]＆＃34;＆gt; {{item}}＆＃34;）

说明

我遇到了一个奇怪的问题，我试图在我的应用程序中使用* ngFor，但它不会在任何可能的组合中工作。我尝试使用BrowserModule，CommonModule。都失败了。任何想法，为什么我不能让这个工作？

nav.component.ts

import {OnInit, Component} from '@angular/core';

@Component({
    selector: 'global-nav',
    template: `
        <div *ngFor="let item of [1, 2, 3]">
            {{item}}
        </div>
    `
})

export class NavComponent implements OnInit {

    private navigation;

    constructor() {
        this.navigation = 
        [
            {
                "href": "#homepage",
                "label": "Homepage"
            }
        ]
    }
    ngOnInit() {

    }
}

app.module.ts

import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { CommonModule } from '@angular/common';
import { BrowserModule } from '@angular/platform-browser';
import { RouterModule, Routes } from '@angular/router';

import { AppComponent } from './app.component';

import { NavComponent } from './components/global/nav/nav.component';
import { MainComponent } from './components/main/main.component';

const appRoutes: Routes = [
  {
    path: '',
    component: MainComponent,
    data: { title: 'Homepage' }
  },
  {
    path: '**',
    redirectTo: '',
    pathMatch: 'full'
  }
];

@NgModule({
  declarations: [
    AppComponent,
    NavComponent,
    MainComponent
  ],
  imports: [
    RouterModule.forRoot(
      appRoutes
    ),
    BrowserModule
  ],
  providers: [],
  schemas: [ CUSTOM_ELEMENTS_SCHEMA ],
  bootstrap: [ AppComponent ]
})
export class AppModule {}

app.component.ts

不需要它只用于设置标题的代码。

的package.json

我的想法已经不多了，我无法找到任何相关信息。也许有人可以帮助我。

修正：

Webpack正在将我的模板变成小写。所以我的所有* ngFor都成了* ngfor

*ngFor won't work when used in imported component

您可以尝试更改AppModule上的导入顺序，以便BrowserModule位于RouterModule之前吗？

编辑/更新（可见度）：

看起来与此issue相关。

* ng在导入组件中使用时不会起作用
