Question

我有以下ts代码。

#home.ts
import {Page, NavController} from 'ionic-framework/ionic';

@Page({
  templateUrl: 'build/pages/home/home.html'
})
export class HomePage {
  constructor(nav: NavController){
  }
}

我收到以下错误。

Error: Cannot resolve all parameters for 'HomePage'(?). Make sure that all the parameters are decorated with Inject or have valid type annotations and that 'HomePage' is decorated with Injectable.
    at NoAnnotationError.BaseException [as constructor]

我查看了FAQ，ionic NavController example和documentation。但我无法发现为什么抱怨的错误。对我来说，似乎我正确导入一切。

我可能做错了什么？
