Question

我想在我的angular t项目中使用 MatPaginatorModule 但我收到错误：

无法绑定到＆＃39; pageSize＆＃39;因为它不是“pa-paginator”的已知属性

1。如果＆＃39; mat-paginator＆＃39;是一个Angular组件，它有＆＃39; pageSize＆＃39;输入，然后验证它是否是该模块的一部分。 ...............

HTML

  <mat-paginator #paginator
             [pageSize]="10"
             [pageSizeOptions]="[5, 10, 20]"
             [showFirstLastButtons]="true">
   </mat-paginator>

我在app.module.ts中导入了模块

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 { }

我正在使用angular5

Answer 1

@Kumail，从你发布的片段看，一切都很好。

虽然只有在未链接所需模块时才会出现此错误。我能想到的唯一原因是，修改后你可能没有保存app.module.ts文件。我确实按照所有步骤将MatPaginatorModule集成到测试项目中并且它工作正常。然后我嘲笑将该模块包含在app.module.ts中但未保存更改。这次我收到你发布的错误。尝试保存，如果您在修改app.module.ts文件后可能错过了。

Answer 2

如果在执行测试时出现错误，则需要在test / spec文件中导入。（app.component.spec.ts）

Angular5材料Paginator无法正常工作
