Error encountered during the deployment of Ionic 3 with TypeScript

After completing the development of my app, I ran it on ionic serve without any issues. However, when compiling the app, I encountered the following error message. Any assistance in resolving this matter would be greatly appreciated.

[15:40:08] typescript error 
            Type ResultPage in C:/Users/Omar/Desktop/InfoKing/src/pages/result/result.ts is part of the declarations of
            2 modules: AppModule in C:/Users/Omar/Desktop/InfoKing/src/app/app.module.ts and ResultPageModule in
            C:/Users/Omar/Desktop/InfoKing/src/pages/result/result.module.ts! Please consider moving ResultPage in
            C:/Users/Omar/Desktop/InfoKing/src/pages/result/result.ts to a higher module that imports AppModule in
            C:/Users/Omar/Desktop/InfoKing/src/app/app.module.ts and ResultPageModule in
            C:/Users/Omar/Desktop/InfoKing/src/pages/result/result.module.ts. You can also create a new NgModule that
            exports and includes ResultPage in C:/Users/Omar/Desktop/InfoKing/src/pages/result/result.ts then import
            that NgModule in AppModule in C:/Users/Omar/Desktop/InfoKing/src/app/app.module.ts and ResultPageModule in
            C:/Users/Omar/Desktop/InfoKing/src/pages/result/result.module.ts.

Answer №1

If you delete the result.module.ts and eliminate the @IonicPage declaration from the result.ts file, then try running it once more. Hopefully, this solution will work for you.
