Angular 4 slim scroll is not working

Question

I'm using Angular 4 slim scroll (https://www.npmjs.com/package/angular4-slimscroll) for my angular 4 project, it's compiling the application successfully but in browser am getting the following error. Can anyone try to help me to find the issue?

Uncaught Error: Unexpected value 'SlimScroll' declared by the module 'AppModule'. Please add a @Pipe/@Directive/@Component annotation.

my package.json file is here.

have you added this in app.modules.ts? If You do. Can you add the code off app.modules.ts? In app.modules.ts Yuo have to add in the part of imports:

import {SlimScroll} from 'angular4-slimscroll';

and, In the part of @NgModule:

@NgModule({
  declarations: [
      ...,
 SlimScroll

  ],
