抱怨存在对象的类型脚本不存在

CartComponent#removeetem():

public removeItem(itemId:string) {
    this.cartService.removeItem(itemId).subscribe(cart => {
      console.log('CartComponent#removeItem', )
      this.cartItems = cart.cartItem;
    });
  }

Typescript为cart.cartItem提供了以下错误:

[ts] Property 'cartItem' does not exist on type 'void'.
any

我已经在另一个应用程序中完成了这项工作,它工作得很好。

CartService移除项()

public removeItem(itemId:string) {
   console.log('CartService#removeItem', itemId)
   return this.httpClient.delete<Cart>(`${this.cartItemUrl}${itemId}`)
   .pipe(
     tap(cart => console.log('cart@removeItem', cart)),
     // map(cart => this.cart = cart, this.setItemCount()),
     map(cart => {
       this.cart = cart;
       this.setItemCount();
     }),
     catchError(this.handleError.bind(this))
   )
 }
