Inheritance In Components Makes Build Error

I have a parent Component like this:

import { Component} from '@angular/core';

@Component({
    selector: 'app-main-parent',
    template: '',
})
export class ParentComponent {
    constructor(protected service) {
        service.doSomething();
    }
}

and a child Component that extends parent:

import { Component} from '@angular/core';
import { ChildService} from './services';

@Component({
    selector: 'app-main-child',
    templateUrl: './child.component.html',
})
export class ChildComponent extends ParentComponent{

    constructor(private _childService: ChildService) {
        super(_childService);
    }
}

and in main.module.ts added these components:

import { NgModule } from '@angular/core';
import { ParentComponent,
        ChildComponent } from './components'

@NgModule({
    imports: [
	...
    ],
    declarations: [
        ParentComponent,
        ChildComponent,
        ...
    ],
    providers: [
	...
    ]
})
export class MainModule { }

I build project with following command:

npm run build

And got this Error:

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory npm ERR! code ELIFECYCLE npm ERR! errno 3 npm ERR! proj.panel@0.0.0 build: ng build --aot --prod --stats-json npm ERR! Exit status 3 npm ERR! npm ERR! Failed at the proj.panel@0.0.0 build script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\user\AppData\Roaming\npm-cache_logs\2018-01-17T10_37_32_166Z-debug.log

If I remove ParentComponent from main.module.ts, then get this Error:

Cannot determine the module for class ParentComponent in C:/Users/user/source/repos/proj/web-panel/app/main/components.ts! Add ParentComponent to the NgModule to fix it.

Other Stuff:

if I run project with npm start command it works fine. only in build I got these Errors.

I ran build command with no aot (ng build --no-aot --prod) but errors are still there.

I dont use ParentComponent anywhere but for childs components to extend.
