如何在 angular4 项目中导入 angular2-cookie

Question

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"
},
"private": true,
"dependencies": {
"@angular/animations": "^4.0.0",
"@angular/common": "^4.0.0",
"@angular/compiler": "^4.0.0",
"@angular/core": "^4.0.0",
"@angular/forms": "^4.0.0",
"@angular/http": "^4.0.0",
"@angular/platform-browser": "^4.0.0",
"@angular/platform-browser-dynamic": "^4.0.0",
"@angular/router": "^4.0.0",

},

"protractor": "~5.1.0",
"ts-node": "~2.0.0",
"tslint": "~4.5.0",
"typescript": "~2.2.0"
}
}

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

我在app.module.ts中导入angular2-cookie：

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

我的项目与ng server配合得很好，在我的铬中也运行良好。

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

ERROR Error: No provider for CookieOptions! 

如何解决这个问题？谢谢大家！

Answer 1

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