如何在Angular 5中配置ngx-cookie-service

Question

我在项目的根模块中安装了ngx-cookie-service

npm i --save ngx-cookie-service

并在app.module

中导入如下

import { CookieService } from "ngx-cookie-service";

@NgModule({
    imports: [BrowserModule, AppRoutingModule, BrowserAnimationsModule],
    declarations: [AppComponent], 
    providers: [CookieService],
    bootstrap: [AppComponent]
})
export class AppModule { }

和systemjs.config如下：

    'ngx-cookie-service': 'npm:ngx-cookie-service/cookie-service/cookie.service.js'

我收到以下错误

(SystemJS) XHR error (403) loading https://127.0.0.1:470/node_modules/ngx-cookie-service/cookie-service
