When trying to serve my application I get the following error:

ERROR in ./node_modules/ngx-responsive/src/index.ts

import { ResponsiveModule } from 'ngx-responsive';
import { AppRoutingModule } from './app-routing.module';

import { AppComponent } from './app.component';

  imports: [
    BrowserModule,

export class AppModule { }

I read in this topic that having TS files in the node_modules folder goes against how libraries should be packaged: libraries should never ship their source .ts files.

I’m not sure if this might be the root of the problem. Anyone else with the same issue?
