ionic cordova build android --prod

i got a new error with ionic when we create a build for production using command

ionic cordova build --prod

it always gives an error at the point of ngc started

Running app-scripts build: --prod

[15:00:23]  build prod started ... 
[15:00:23]  clean started ... 
[15:00:23]  clean finished in 36 ms 
[15:00:23]  copy started ... 
[15:00:23]  ngc started ... 
Error: Type DashboardPage in /Users/sunny/Desktop/Apps/IONIC/MintOld/src/pages/dashboard/dashboard.ts
is part of the declarations of 2 modules: AppModule in
/Users/sunny/Desktop/Apps/IONIC/MintOld/src/app/app.module.ts and
DashboardPageModule in /Users/sunny/Desktop/Apps/IONIC/MintOld/src/pages/dashboard/dashboard.module.ts! 
Please consider moving DashboardPage in
/Users/sunny/Desktop/Apps/IONIC/MintOld/src/pages/dashboard/dashboard.ts to a 
higher module that imports AppModule in
/Users/sunny/Desktop/Apps/IONIC/MintOld/src/app/app.module.ts and 
DashboardPageModule in /Users/sunny/Desktop/Apps/IONIC/MintOld/src/pages/dashboard/dashboard.module.ts. 
You can also create a new NgModule that exports and includes DashboardPage in
/Users/sunny/Desktop/Apps/IONIC/MintOld/src/pages/dashboard/dashboard.ts
then import that NgModule in AppModule in 
/Users/sunny/Desktop/Apps/IONIC/MintOld/src/app/app.module.ts 
and DashboardPageModule in /Users/sunny/Desktop/Apps/IONIC/MintOld/src/pages/dashboard/dashboard.module.ts.

It's because of you have declared the DashboardPage in two modules, If you are using this.navCtrl.push("DashboardPage"), then remove DashboardPage from app.module.ts file under declatrations, or if you are using this.navCtrl.push(DashboardPage), then delete the dashboard-page-module file.

I got the same error too. I just solved it by closing all ionic tasks running in parallel and deleting the www folder from my project folder.

I then just ran

ionic cordova build android

and then

ionic cordova build android --prod --release

And it worked. I don't know how / why , but doing it like this I did not get that error

As the error says you're importing your module 2 times, maybe you have done lazy loading pages and forgot to delete the import of your module from app.module.ts

So if you're using lazy loading modules, go to your app.module.ts and look for your imported DashboardPage in Declarations and/or entryComponents array, if they're there just delete the DashboardPage from them.

If you're not lazy loading you'll need to delete the dashboard.module.ts file.

You can't have the page module imported to a same level @NgModule, that's what you're doing wrong.

Hope this helps.
