属性 'then' 在类型 'void' 上不存在

Property 'then' does not exist on type 'void'

我应该如何处理 Typescript 错误:

Property 'then' does not exist on type 'void'

我的代码如下所示:

import {Component} from '@angular/core';
import {SocialSharing} from "ionic-native";

@Component({
  templateUrl: 'build/pages/about/about.html'
})
export class AboutPage {

  constructor() {

  }

  share() {
    SocialSharing.share('Take a look at our app. It is great! Download it from the App Store now.',
        'Take a look at our app. It is great! Download it from the App Store now.', null, null).then(
          res => {},
          err => {}
    );
  }

}

函数的定义share returns void 也可以在错误信息中看到

static share (message?: string, subject?: string, file?: string|Array<string>, url?: string): void {}

因此你不能在调用share时调用then
