在Angular5问题中的ng-select：ERROR TypeError：Object(…)不是NgDropdownPanelComponent.ngOnInit(ng-select.js)中的函数

我在我的项目angular5中使用Ng-SELEct 2.0.0,如 this link所示
,我可以从api休息弹簧启动得到结果,但我正在解决一个问题我得到这个错误,而我点击ng-SELEct：

ERROR TypeError: Object(...) is not a function
at NgDropdownPanelComponent.ngOnInit (ng-SELEct.js:1450)
at checkAndupdateDirectiveInline (core.js:12352)
at checkAndupdateNodeInline (core.js:13876)

而且我也不能选择我想要的信息(在这种情况下属性’nom’),就像ng SELEct被阻止或者像这样的东西.

这是我的project.component.HTML代码

<ng-SELEct  *ngIf="_listClients"
             [items]="listClient"
              bindLabel ="nom"
              bindValue ="id"
            [(ngModel)]="SELEctedPersonId">

</ng-SELEct>

<p>
  SELEcted city ID: {{SELEctedPersonId | json}}
</p>

这是文件project.component.ts

import {Component,OnInit,ViewChilD} from '@angular/core';
import {ActivatedRoute,Router} from '@angular/router';
import {ProjetservicE} from '../../../../../service/projet.service';
import {Projet} from '../../Models/Projet';
import { ModalDirective } from 'ngx-bootstrap/modal';
import 'rxjs/add/operator/map';
import {ClientservicE} from '../../../../../service/client.service';

@Component({
  SELEctor: 'app-projects',templateUrl: './projects.component.html',styleUrls: ['./projects.component.scss']
})
export class ProjectsComponent implements OnInit {

  SELEctedPersonId:number = null;
  _listClients :any;


constructor(private router:router,private projetSevice:Projetservice,private clientServ:Clientservice,private route: ActivatedRoutE) { }

ngOnInit() {

       this.CLIENtList();
  }


get listClient() {
     return this._listClients ? this._listClients.map(item => {
      return {id: item.id,prenom : item.prenom,nom : item.nom}
    }) : [];
  }


  clientList(){

     this.CLIENtServ.getListClients()
       .subscribe((data:any)=>{
        this._listClients=data;
       },err=>{
         console.log('this is error ');
       })

  }

}
