使用[cdkDropListData]时，在控制台上出现错误，无法绑定到‘cdkDropListData’，因为它不是‘div’的已知属性。

我是新手，所以请避免新手行为

我已经在mode.ts中导入了CDkDragDrop
这是组件文件。

import {Component, NgModule} from '@angular/core';
import {StudentModel} from '../model/studentRepository.model';
import {Student} from '../model/student.model';
import {CdkDragDrop, DragDropModule, moveItemInArray, transferArrayItem} from '@angular/cdk/drag-drop';

@Component({
  selector: 'student-selector',
  templateUrl: 'studentSelector.component.html',
  styleUrls: ['./studentSelector.component.css']
})

export class StudentSelector {
  boys =  [];
  girls = [];
  constructor(private dataModel: StudentModel) {
    this.boys = dataModel.getStudents();
    this.girls = dataModel.getStudents();

  }
  get students(): Student[] {
    return this.dataModel.getStudents();
  }
  conva = [];

  drop(event : CdkDragDrop<string[]>){
    transferArrayItem(event.previousContainer.data,
      event.container.data,
      event.previousIndex,
      event.currentIndex);
  }
}

这是模块文件。

import {NgModule} from '@angular/core';
import { StudentModel } from './studentRepository.model';
import { SimpleDataSource } from './datasource.model';
import {DragDropModule} from '@angular/cdk/drag-drop';

@NgModule({
  providers: [StudentModel,SimpleDataSource],
  imports : [DragDropModule]
})

export class ModelModule {

}
