Still facing the issue Uncaught (in promise): Error: StaticInjectorError Any solution on it.

Using Angular cli 1.5.4 and Angular 5.0.0 Created the service library which contained the httpclient.post() call and create the package using ng-packager. In consumer app added the service library package using npm.

On run time when we run the application it throw the error Uncaught (in promise): Error: StaticInjectorError No provider for httpclient

If we tested the service library code without consuming in any application it work as expected. when we consumed in any application and run that application it throw the run time error

Also try preserveSymlinks in angular.cli.json file in consumer application however no success still the error present run time. “defaults”: { “styleExt”: “css”, “build”: { “preserveSymlinks”: true }, “component”: {} } ***Service code application name - CommonApp

test.service.ts simply added the httpClient in constructor,

@Injectable() export class TestService {

constructor(private httpClient: HttpClient) { }
getData(){
    return 'Hello World';
}

}

The issue is resolved Updated angular cli and added “build”: { “preserveSymlinks”: true }, It’s working now.

I spoke too soon… looks like this is a preserveSymlinks thing helps, because I was testing the inclusion of my lib into a new dummy test app. This helps in debugging, but is this preserveSymlinks thing only a problem because of the npm link? (Should I be able to move forward and expcet my library to be installed into a new app from npm and just work?)
