无法将类型“ MatSelect”的参数分配给类型“ MatChipInputEvent”的参数

Question

尝试构建项目时出现此错误

---

'MatSelect'类型的参数不能分配给'MatChipInputEvent'类型的参数。   类型“ MatSelect”中缺少属性“输入”。

<div class="col-sm-12 col-md-4 col-xl-4  pb-4">
<button mat-raised-button type="button" color="primary"
    (click)="addSomething(objectHere)" [disabled]="loading">
    <mat-icon matListIcon>add</mat-icon>
    Add Something Button
</button>
