我写了一篇关于问题的新文章以提供更多详细信息。Ionic 2:“属性号”在类型'typeof'上不存在
我尝试在我的离子2项目,创建一个类,我用这个代码:
import { Component } from '@angular/core';
@Component({
templateUrl: 'field.html'
})
export class test {
x : number;
constructor(x : number){
this.x = x;
}
}
我想在我的其他组件来使用它。它在我的终端中用“离子服务”进行编译时起作用。但是,当我尝试在我的android手机上编译我有这个错误:
[09:54:06] Error at C:/xampp/htdocs/AppFineMobile/.tmp/classes/fieldSpecs/test.ngfactory.ts:42:71

我不明白为什么。首先我在提供者文件上尝试相同的代码,但同样的问题。
有人有什么想法吗?
而不是这样做,只需使用'constructor(private x:number){// ...}'。通过这样做,您不需要在组件中声明'private'属性,因为typescript正在为您声明它。 – sebaferreras
好的,谢谢我改变了这一点。但这不是解决方案。 :) –
当然,这就是为什么它只是一个评论,而不是答案:) – sebaferreras
