你错过了Formsmodule。试着像这样导入-

import {FormsModule} from '@angular/forms';

并像这样在AppModule中使用它-

@NgModule({
  imports: [ BrowserModule, FormsModule, NgbModule ],

您也可以像这样使用ngbDatepicker-

<input class="form-control" placeholder="yyyy-mm-dd" name="dp1" [(ngModel)]="newItem.EndTime"  ngbDatepicker #d1="ngbDatepicker" required>
