node.js - Ionic2 typescript 设备构建错误 'uglifyjs failed: SyntaxError: Unexpected token operator «=», expected punc «,»`

Question

我正在尝试在 Ionic 应用程序中创建 360 度视频播放器。我的代码如下。

HTML:

<ion-content>
    <video id="videojs-panorama-player" class="video-js vjs-default-skin" src=""  crossorigin="anonymous" controls ref="player">
        <source src="/assets/beach.mp4" type='video/mp4'>
    </video>
</ion-content>

typescript :

import { Component } from '@angular/core';
import { NavController, Platform } from 'ionic-angular';
import videojs from 'video.js';
import panorama from 'videojs-panorama';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})

export class HomePage {

    private player: any;

    constructor(public navCtrl: NavController, private platform: Platform) {
        this.player = null;
        this.platform.ready().then(() => {
             this.init();
        });
    }

    init() {
        this.player = videojs('videojs-panorama-player', {},  () => {
            window.addEventListener("resize", () => {
                var canvas = this.player.getChild('Canvas');
                if(canvas) canvas.handleResize();
            });
        });
        this.player.width(960), this.player.height(400);
        panorama(this.player, {
            clickToToggle: false,
            autoMobileOrientation: true,
            initFov: 100,
            VREnable: true,
            clickAndDrag: true,
            NoticeMessage: "touch to interact"
        });
        console.log("initialized");
    }
}

当我ionic serve 时，这段代码按预期工作，但是当我尝试构建一个平台时，我遇到了很多问题。 (ionic build ios 或 ionic build android)。

错误开始时记录:

我更新了我的 NPM、Node.js 和 sass。可能是什么问题呢？关于如何解决它的任何想法？非常感谢。

我发现了问题。问题是 videos-panorama 不适用于某些 Typescript 绑定(bind)。我联系了开发人员，他更新了它，所以现在这段代码工作正常。祝你好运!
