在Ionic Application中进行生产构建时出错

Question

在我的android设备上进行生产测试时，出现以下错误：

    Uncaught ReferenceError: Must call super constructor in derived class before 
accessing 'this' or returning from derived constructor
        at new <anonymous> (main.js:1)
        at t.create (vendor.js:1)
        at vendor.js:1
        at t.invoke (polyfills.js:3)
        at Object.onInvoke (vendor.js:1)
        at t.invoke (polyfills.js:3)
        at r.run (polyfills.js:3)
        at t.run (vendor.js:1)
        at e._bootstrapModuleFactoryWithZone (vendor.js:1)
        at e.bootstrapModuleFactory (vendor.js:1)

问题是我不知道原因是什么，因为无法从此错误消息中分辨出来。

我的组件列表：

Pages:
    LoginPage <--- starting page
    SignupPage,
    CalendarPage,
    SettingsPage,
    WorkTimePage,
    RestorePasswordPage,
    ChangePasswordPage,
    NotificationsPage,
    TrackerPage,
    EmptyTrackerPage,
    CreateProjectContentPage,
    MenuTakenSlotContentPage,
    EmptySlotContentPage,
    TakenSlotContentPage,
    ColorPickerContentPage,
    ProjectSelectContentPage,
    TimeConfirmContentPage,
    MenuOfflineWorkContentPage,
    CalendarEventSelectContentPage,
    AgreementContentPage,
    ProjectsPage,
    IntroductionPage,
    ProjectDetailsContentPage,
    WeekSwapContentPage,
    WorkTimeSwapContentPage,
    SettingsSelectContentPage,
    ModalPage

Providers: 
    Settings, 
    Auth, 
    Data,
    Connectivity

我该如何解决？或者至少如何检查出什么问题？

这是发生错误的地方：

constructor(t) {} <----- here
        get _BrowserXhr_29() {
            return null == this.__BrowserXhr_29 && (this.__BrowserXhr_29 = new p.c),
            this.__BrowserXhr_29
        }
