Hi Sahal,
Good day to you.
We have checked with your query and suspect that the reported issue (“ng build --prod produces build error”) may be caused due to lower version of angular devkit version is referred in your application since this package is newly introduced in Angular 6.0 and angular cli version is not optimized in this version.
So, we suggest you update the angular dev kit version to V0.10.7 ("@angular-devkit/build-angular": "0.10.7"), since this version is compatible for angular 6 to get rid of the reported issue at your end. We have prepared the sample with mentioned version. Please find the sample from the below link.
Still issue persists, please revert with issue reproducing sample (if possible) or package.json, app.component.ts and app.module.ts file that will help us to check and resolve the issue earliest.
Regards,
Ashokkumar B.
