【问题描述】：

我在 Angular 4 应用程序中实现基本路由，在浏览器上加载应用程序时出现以下错误。我已经在 approuting.module 中定义了路由，同时也引用了 Ngmodule 中的路由器模块以及 approuting.module。不知道是什么问题

Can't bind to 'routerLink' since it isn't a known property of 'a'.

Can't bind to 'routerLink' since it isn't a known property of 'a'. ("ew" [hidden]="!dataItem.isVisibleView">
                                                        <a [ERROR ->][routerLink]="['/view', dataItem.movieId, 'responses']" routerLinkActive="active"><i class="fa fa-fil"): ng:///MovieModule/MovieComponent.html@85:59
Can't bind to 'routerLink' since it isn't a known property of 'a'. ("it" [hidden]="!dataItem.isVisibleEdit">
                                                        <a [ERROR ->][routerLink]="['edit', dataItem.movieId]" routerLinkActive="active"><i class="fa fa-pencil" aria-hidd"): ng:///MovieModule/MovieComponent.html@92:59

以下是我的应用程序的源代码

【问题讨论】：

尝试将BrowserModule 移到导入的顶部？或者至少高于AppRoutingModule。

那没有帮助

您的代码看起来正确，确保所有内容都正确编译，我将停止所有ng serve 或ng build -w 和rd /s /q node_modules（或rm -rf node_modules，如果在Linux 上），然后@987654331 @看看

完全按照您的建议进行了尝试，但仍然出现同样的问题。看起来链接没有正确建立

如果我只评论锚标签，请注意页面加载

【参考方案1】：

我已经设法解决了这个问题。我必须将路由器模块添加到电影模块的导入中，因为电影模块中引用了路由器链接

【参考方案2】：

导入路由器模块

从'@angular/router'导入RouterModule；

import  NgModule  from '@angular/core';
import  RouterModule  from '@angular/router';

import  FormsModule, ReactiveFormsModule  from '@angular/forms';

import  LayoutComponent  from './layout/layout.component';

@NgModule(
  imports: [
    RouterModule,
    FormsModule,
    ReactiveFormsModule,
  ],
  declarations: [
    LayoutComponent
  ],
  exports: [
    FormsModule,
    ReactiveFormsModule,
  ],
  entryComponents: []
)
export class SharedModule  

【讨论】：

只需要导入和你类似的RouterModule即可。 :)

【参考方案3】：

只是添加我的情况略有不同。也许它可以帮助别人。

正如大家在我发现的所有帖子中解释的那样......

AppRoutingModule：

  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]

其他路由模块：

  imports: [RouterModule.forChildren(routes)],
  exports: [RouterModule]

Home 模块有一个带有 routerLink 的模板：

<a [routerLink]="'asdf'">asdf</a>

以下是发生错误的情况。请注意，应用正在延迟加载其他模块：

const routes: Routes = [
   path: 'home',
    loadChildren: () => import('./pages/home/home-routing.module')
            .then(m => m.HomeRoutingModule) //**wrong!**
  
]

这是解决的情况，因为我导入了错误的模块：

应用正在延迟加载其他模块：

const routes: Routes = [
   path: 'home',
    loadChildren: () => import('./pages/home/home.module')
            .then(m => m.HomeModule)
  
]
