compiler.js:2427 Uncaught Error: Template parse errors:

我尝试过的事情：

 <mat-label>Date</mat-label>
         <input name="salesDate" matInput [matDatepicker]="salesDate" placeholder="Select a date" [(ngModel)] = "api.SHeader.salesDate | date:'dd/MM/yyyy'" (ngModelChange)="api.SHeader.salesDate= $event"  >
         <mat-datepicker-toggle matSuffix [for]="salesDate"></mat-datepicker-toggle>
         <mat-datepicker #salesDate></mat-datepicker>
     </mat-form-field>
