angular - Uncaught Error : Unexpected directive 'angular-material' imported by the module 'MyMaterialModule' . 请添加 @NgModule 注释。 Angular 5

Question

我一直有这个错误

Uncaught Error: Unexpected directive 'MatPaginator' imported by the module 'MaterialModule'. Please add a @NgModule annotation.

这是我的 Material 模块

import { NgModule, ViewChild } from '@angular/core';
import { CommonModule } from '@angular/common';
import { MatPaginator, MatSort, MatTableDataSource,MatButtonModule, 
MatTableModule } from '@angular/material';

@NgModule({
    imports: [MatButtonModule,MatTableModule,
              MatPaginator, MatSort, 
              MatTableDataSource],
    exports: [MatButtonModule,MatTableModule,MatPaginator, MatSort, 
             MatTableDataSource],
})
export class MaterialModule { }

这是我的 app.module

...
import { MaterialModule } from './material.module';


@NgModule({
  declarations: [
     ...

  ],
  imports: [
    ...
    MaterialModule,
    ...
  ],
  providers: [...],
  bootstrap: [ AppComponent]
})
export class AppModule { }

这也是我的观点

<div class="example-container mat-elevation-z8">
   <div class="example-header">
     <mat-form-field>
      <input matInput (keyup)="applyFilter($event.target.value)" 
    placeholder="Filter">
    </mat-form-field>
  </div>

<!-- Name Column -->
<ng-container matColumnDef="name">
  <mat-header-cell *matHeaderCellDef> Name </mat-header-cell>
  <mat-cell *matCellDef="let user"> {{user.name}} </mat-cell>
</ng-container>

<!-- Weight Column -->
<ng-container matColumnDef="email">
  <mat-header-cell *matHeaderCellDef> email </mat-header-cell>
  <mat-cell *matCellDef="let user"> {{user.email}} </mat-cell>
</ng-container>

<!-- Color Column -->
<ng-container matColumnDef="phone">
  <mat-header-cell *matHeaderCellDef> phone </mat-header-cell>
  <mat-cell *matCellDef="let user"> {{user.phone}} </mat-cell>
</ng-container>

<ng-container matColumnDef="company">
  <mat-header-cell *matHeaderCellDef> company </mat-header-cell>
  <mat-cell *matCellDef="let user"> {{user.company.name}} </mat-cell>
</ng-container>

<mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
<mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>

我从 angular material documentation我该如何解决？

Answer 1

我有同样的问题。我导入了 MatPaginatorModule在我的@NgModule进入导入数组。
它解决了我的问题。我希望它也适合你。
