Erro ao importar um modulo no modulo principal

Estou criando uma aplicacao sobre uma biblioteca aonde usuarios emprestam livros, no meu modulo de livros BookModule quero que tenha os components bookList.component e registerBook.component e ai meu AppModule importe o BookModule para usar os componentes dele. O problema e que quando faco isso da o seguinte erro "Can't bind to 'routerLink' since it isn't a known property of 'a'." Vou deixar o codigo dos componentes e modules aqui. bookList.component

import { Component, Inject } from "@angular/core";
import { Http } from "@angular/http";

@Component({
    moduleId: module.id,
    templateUrl: './bookList.component.html'
})

export class BookListComponent{
    books: Object[] = [];

    constructor(http: Http){
        http
        .get("http://localhost:52637/api/books")
        .map(response => {
            return response.json();
        })
        .subscribe(books => {
            this.books = books;
        }, error => console.log(error));
    }
}

registerBook.coponent

import { Component } from "@angular/core";

@Component({
    moduleId: module.id,
    templateUrl: './registerBook.component.html'
})

export class RegisterBookComponent{}

app.routes

import { RouterModule, Routes } from "@angular/router";
import { AppComponent } from "./app.component";
import { BookModule } from "./book/book.module";
import { RegisterBookComponent } from "./book/registerBook.component";
import { BookListComponent } from "./book/bookList.component";

const appRoutes: Routes = [
    { path: 'book', component: RegisterBookComponent },
    { path: 'books', component: BookListComponent }
];

export const routing = RouterModule.forRoot(appRoutes);

BookModule

import { NgModule } from "@angular/core";
import { BookListComponent } from "./bookList.component";
import { RegisterBookComponent } from "./registerBook.component";


@NgModule({
    declarations: [BookListComponent, RegisterBookComponent],
    exports: [BookListComponent, RegisterBookComponent]
})

export class BookModule{}

AppModule

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { BookModule } from "./book/book.module";
import { routing } from "./app.routes";
import { HttpModule } from "@angular/http";
import 'rxjs/add/operator/map';

@NgModule({
  imports: [
    BrowserModule, routing, HttpModule, BookModule
  ],
  declarations: [
    AppComponent
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }
