我正在尝试在我的 angular4 项目中导入 angular2-cookie。

我的项目是用 angular-cli@1.2.7 构建的，这是我的package.json：

{
  "name": "ng-admin",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",
    "start": "ng serve --port 4201",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },

  }
}

angular2-cookie dochttps://github.com/salemdar/angular2-cookie#cli要求我添加一些东西，angular-cli-build.js但我既没有angular-cli-build.js也没有systemjs.config.js

我导入angular2-cookie：app.module.ts

import { CookieService } from 'angular2-cookie/services/cookies.service';
...
...
providers: [
    CookieService
 ]

我的项目运行良好，ng server并且在我的 chrome 中运行良好。

它是用 成功构建的ng build --prod，但是当我在 chrome 中运行它或用 运行它时ng server --aot，chrome 控制台显示此错误：

ERROR Error: No provider for CookieOptions!

我怎么解决这个问题？谢谢大家！

在导入语句中添加 CookieOptions，例如 import { CookieService, CookieOptions } from 'angular2-cookie'; 然后将 CookieService 和 CookieOptions 添加到根模块的提供程序数组中。
