编译模板时出错。装饰器不支持函数表达式

Question

我已经在我的离子v4应用程序中实现了信号，在调试测试中一切都很完美但是在生产时，在android和ios中，我都会收到错误并停止编译。

ionic cordova build android --prod --release

ionic cordova build ios --prod

在这两种情况下，终端显示相同的错误

ERROR in app/app.module.ts(66,5): Error during template compile of 'AppModule'
Function expressions are not supported in decorators in 'OneSignal'
'OneSignal' references 'ɵ2'
'ɵ2' contains the error at ../@ionic-native/onesignal/ngx/index.js.ts(64,32)
Consider changing the function expression into an exported function.

这是@ ionic-native / onesignal / ngx / index.js.ts中函数的代码

我发布了答案，因为我修复了错误。标志--prod最小化并优化了项目，包括提高性能的AoT（Ahead-of-time）。它是AoT导致与OneSignal插件的冲突。解决方案是在没有--prod的情况下进行编译，只使用标志--release。我正在调查是否有可能使用--prod编译除了AoT，但至少现在，这是一个很好的解决方案，另一方面我的应用程序工作得非常快。
