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",

"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e"
},
"private": true,
"dependencies": {

"@angular/common": "^4.0.0",
"@angular/compiler": "^4.0.0",

},

"protractor": "~5.1.0",
"ts-node": "~2.0.0",
"tslint": "~4.5.0",
"typescript": "~2.2.0"
}
}
angular2-cookie 文档 https://github.com/salemdar/angular2-cookie#cli让我在 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
]
我的项目在 ng server 上运行良好，在我的 chrome 上也运行良好。
它使用 ng build --prod 成功构建，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!
我该如何解决这个问题？谢谢大家!
最佳答案
在您的导入语句中添加 CookieOptions，例如 import { CookieService, CookieOptions } from 'angular2-cookie';然后在根模块的提供程序数组中添加 CookieService 和 CookieOptions。
