Type AboutPage in G:/ion/cam/src/pages/about/about.ts is part of the declarations of 2 modules: AppModule in
G:/ion/cam/src/app/app.module.ts and AboutPageModule in G:/ion/cam/src/pages/about/about.module.ts! Please
consider moving AboutPage in G:/ion/cam/src/pages/about/about.ts to a higher module that imports AppModule
in G:/ion/cam/src/app/app.module.ts and AboutPageModule in G:/ion/cam/src/pages/about/about.module.ts. You
can also create a new NgModule that exports and includes AboutPage in G:/ion/cam/src/pages/about/about.ts
then import that NgModule in AppModule in G:/ion/cam/src/app/app.module.ts and AboutPageModule in
G:/ion/cam/src/pages/about/about.module.ts.
