Angular5 material Paginator is not working - angular-material

Question

I want to use MatPaginatorModule in my angular t project but i am getting error:
Can't bind to 'pageSize' since it isn't a known property of 'mat-paginator'
1. If 'mat-paginator' is an Angular component and it has 'pageSize' input, then verify that it is part of this module.
...............
html
<mat-paginator #paginator
[pageSize]="10"
[pageSizeOptions]="[5, 10, 20]"
[showFirstLastButtons]="true">
</mat-paginator>
i have imported module in my app.module.ts
import { BrowserModule } from '#angular/platform-browser';
import { NgModule } from '#angular/core';
import { AppComponent } from './app.component';
import { GlobalModule } from './global/global.module';
import { ProtectedModule} from './protetcted/protect-module.component';
import { AppRoutingModule } from './app.routing.module';
// import { MatTableModule } from '#angular/material/table';
import { MatPaginatorModule } from '#angular/material';
#NgModule({
declarations: [
AppComponent,
],
imports: [
BrowserModule,
GlobalModule,
ProtectedModule,
AppRoutingModule,
// MatTableModule,
MatPaginatorModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }

Answer 1

#Kumail,
Everything looks fine from the snippets you posted.
Though this error will occur only when the required module is not linked. The only reason I could think of is that, you might not have saved app.module.ts file after modifications. I did follow all the steps to integrate a MatPaginatorModule in a test project and it worked. Then I mocked to include that module in app.module.ts but not saved the changes. This time I got the error you posted. Try saving, If you could have missed after modifying app.module.ts file.

Answer 2

If the error is coming while doing testing, then the imports are needed in the test/spec file. (app.component.spec.ts)
