Angular 获取路由错误，表示没有路由提供程序

./AppComponent类AppComponent-内联模板中的错误：0:0，原因是：路由器没有提供程序

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

请将此添加到app.module.ts中

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { HttpClient, HttpClientModule, HttpClientJsonpModule } from '@angular/common/http';
import { ReactiveFormsModule, FormsModule } from '@angular/forms';

import { AppRoutingModule } from './app-routing.module';

import { GridModule } from '@progress/kendo-angular-grid';
import { LayoutModule } from '@progress/kendo-angular-layout';
import { ButtonsModule } from '@progress/kendo-angular-buttons';
import { DialogModule } from '@progress/kendo-angular-dialog';
import { DropDownsModule } from '@progress/kendo-angular-dropdowns';



@NgModule({
  declarations: [
    AppComponent,
    HeaderComponent,
    FooterComponent,

import { RouterModule, Routes } from '@angular/router';

imports: [
    RouterModule.forRoot([])
    // other imports here
  ]

似乎AppRoutingModule模块中存在问题。 如果您在AppRoutingModule中定义的路线如下

const routes: Routes = [
  { path: '', redirectTo: '/login', pathMatch: 'full'},
 { path: 'login', component: SignInComponent},
  { path: '**', redirectTo: '/login' }
];

那么在AppRoutingModule中，很可能您缺少这样的导入语句

 @NgModule({
      imports: [RouterModule.forRoot(routes)],
    })
