有什么建议吗？
【问题讨论】：
您是否在为您的页面使用延迟加载？请分享您的主要模块和组件 @Sébastien 检查上面我已添加 【参考方案1】：您必须将您的主页添加到 app.module.ts 中的 declarations 和 entryComponents
declarations: [
MyApp,
HomePage,
...
],
....
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HomePage,
...
],
您可能还需要添加其他非延迟加载的页面。延迟加载的页面（有自己的模块的页面），不需要在这里添加。
【讨论】：
这个类还有 loginService, UpComingService, ActiveService, locationCompleteService, FeedbackService, locationService, locationUpdate, invoiceService, scopeofworkservice, ScheduleService, otService 我不懂你们的cmets...什么是主页？ HomePage 是 ionic Page 的一个类。对于以下课程，我也遇到了同样的错误。此类不是 Ionic 页面，此类用于使用 Rest API 从服务中获取数据“loginService, UpComingService, ActiveService, locationCompleteService, FeedbackService, locationService, locationUpdate, invoiceService, scopeofworkservice, ScheduleService, otService” 如果与我的回答无关，请考虑解释您所做的事情。 当然@Sebastine 我会解释【参考方案2】：找到解决办法
正如@Sébastien 提到添加我所做的页面，但我没有使用主页所以我从项目中删除了该页面。对于最新的 Angular 版本，AOT 编译器会扫描整个项目文件夹，因此会混淆使用哪些类，哪些不使用。我将文件添加到声明部分之后，它会引发错误以添加模板。
对于每个组件，我添加了以下代码
@Component(
selector: 'DbLoginService',
template: '<span></span>'
)
就是这样。
@Sébastien 你的回答很有价值
