shared.module.ts

import { NgModule } from "@angular/core";
import { CommonModule } from "@angular/common";
import { SlimScroll } from "angular-io-slimscroll";

@NgModule({
    imports: [
        CommonModule
    ],
    declarations: [
        SlimScroll
    ],
    exports: [
        SlimScroll
    ]
})
export class SharedModule { }

Module that i want to use scroll boot.ts

@NgModule({
    imports: [
        ...
        SharedModule
    ],
    declarations: [
        ....
    ],
    providers: [
        ...
    ],
    bootstrap: [AppComponent],
    exports: [
        ...
    ]
})
export class AppModule { }

this is how i added slimscroll app.html

<div slimScroll
                 width="auto"
                 height="600px"
                 size="7px"> ..... </div>

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

In Angular 4.3.5 i cant import this directive into declaration its not working.
