Angular：带有* ngClass的条件类

我的Angular代码有什么问题？ 我得到： Cannot read property 'remove' of undefined at BrowserDomAdapter.removeClass … <ol class="breadcrumb"> <li *ngClass="{active: step==='step1'}" (click)="step='step1; '">Step1</li> <li *ngClass="{active: step==='step2'}" (click)="step='step2'">Step2</li> <li *ngClass="{active: step==='step3'}" (click)="step='step3'">Step3</li> </ol>
