請問下老師，這樣用了簽字板，在打包的時候會報錯，碰到過嗎？ ionic cordova run android --prod --release， 報如下錯：
[09:27:03] typescript error
Type SignForPcPage in E:/ionic3/lims-mobile-app/src/pages/sign-for-pc/sign-for-pc.ts is part of the
declarations of 2 modules: AppModule in E:/ionic3/lims-mobile-app/src/app/app.module.ts and
SignForPcPageModule in E:/ionic3/lims-mobile-app/src/pages/sign-for-pc/sign-for-pc.module.ts! Please
consider moving SignForPcPage in E:/ionic3/lims-mobile-app/src/pages/sign-for-pc/sign-for-pc.ts to a higher
module that imports AppModule in E:/ionic3/lims-mobile-app/src/app/app.module.ts and SignForPcPageModule in
E:/ionic3/lims-mobile-app/src/pages/sign-for-pc/sign-for-pc.module.ts. You can also create a new NgModule
that exports and includes SignForPcPage in E:/ionic3/lims-mobile-app/src/pages/sign-for-pc/sign-for-pc.ts
then import that NgModule in AppModule in E:/ionic3/lims-mobile-app/src/app/app.module.ts and
SignForPcPageModule in E:/ionic3/lims-mobile-app/src/pages/sign-for-pc/sign-for-pc.module.ts.
