Hi Alex, 

Greetings from Syncfusion support. 

We have checked your query and suspect that the reported issue may occur due to lower version of angular devkit version 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. 

Please let us know if you need further assistance on this.  

Regards, 

Keerthana.
