在我的应用程序angular2 aspnet核心中找不到错误angular2-cookies / core.js

我搜索了2小时左右，我的错误在哪里。这就是原因，我尝试在这里提出我的问题。我有这个错误：

“找不到angular2-cookies / core.js”

我已经使用npm正确安装了angular2-cookie。

这是我的ServiceCookies：

import { Injectable } from '@angular/core';
import {CookieService, CookieOptionsArgs} from 'angular2-cookie/core';

@Injectable()
export class CookiesService {
    private option: CookieOptionsArgs;

    constructor(private cookieService: CookieService) {
    }

    getCookie(key: string) {
        return this.cookieService.get('cookieName');
    }

    setCookie(key: string, value: string) {
        var expiresDate = new Date(new Date().getTime() + 3600 * 1000);
        this.option.expires = expiresDate.toDateString();
        // 10 ans pour le moment 
        this.cookieService.put(key, value, this.option.expires);
    }

    deleteCookie(key: string) {
        this.cookieService.remove(key);
    }
}

这是我的system.config.js，在其中声明运行我的应用程序的路径文件。
