无法绑定到“routerlink”，因为它不是“a”的已知属性（Angular 11 + asp.net core5 + adminlte3）

Question

我正在使用 adminlte3、angular、asp.net core5 编写 Web 应用程序并收到错误消息，但最近几天无法解决此问题。错误消息是“无法绑定到‘routerlink’，因为它不是‘a’的已知属性。~~” 我一直在研究这个问题并遵循了答案，但所有这些答案都不起作用

这是布局：

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { RouterModule } from '@angular/router';
import { AppComponent } from './app.component';
import { NavMenuComponent } from './nav-menu/nav-menu.component';
import { DashV1Component } from './dashboard_v1/dashboard_v1.component';
import { CitiesComponent } from './cities/cities.component';
@NgModule({
  declarations: [
    AppComponent,
    NavMenuComponent,
    CitiesComponent,
    DashV1Component
  ],
  imports: [
    BrowserModule.withServerTransition({ appId: 'ng-cli-universal' }),
    HttpClientModule,
    FormsModule,
    RouterModule.forRoot([
      { path: '', component: DashV1Component, pathMatch: 'full' },
      { path: 'cities', component: CitiesComponent}
    ])
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.Component.ts

import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent {
  
}

Cities.Component.ts

import { Component, Inject } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { City } from './city';
@Component({
  selector: 'app-cities',
  templateUrl: './cities.component.html',
  styleUrls: ['./cities.component.css']
})
export class CitiesComponent {
  public cities: City[];
  constructor(
    private http: HttpClient,
    @Inject('BASE_URL') private baseUrl: string) {
  }
  ngOnInit() {
    this.http.get<City[]>(this.baseUrl + 'api/Cities')
      .subscribe(result => {
        this.cities = result;
      }, error => console.error(error));
  }
}

导航菜单.component.html

<ul class="nav-treeview">
            <li class="nav-item">
              <a class="nav-link" [routerlink]="['/cities']">Cities_R</a>
            </li>  ~~~~~  

导航菜单.component.ts

import { Component } from '@angular/core';
@Component({
  selector: 'app-nav-menu',
  templateUrl: './nav-menu.component.html',
  styleUrls: ['./nav-menu.component.css']
})
export class NavMenuComponent {
}

以下是错误信息

Answer 1

应该是：

<a class="nav-link" [routerLink]="['/cities']">Cities_R</a>

您的代码显示 routerlink 不正确。
