MatToolbar：尝试组合不同的工具栏模式

Question

出现以下错误：

MatToolbar：尝试组合不同的工具栏模式。要么显式指定多个

<mat-toolbar-row>

元素，要么仅将内容放置在单行的

<mat-toolbar>

中。

我的代码已经在 mat-toolbar 中应用了 mat-toolbar-row。然而，该错误仍然存在。

html文件的代码片段如下：

<div class="wallpaper">
<mat-toolbar color="primary">
        <mat-toolbar-row>
         <span>Welcome, User</span>
         <span class="example-fill-remaining-space"></span>
         <span class="align-center"></span>
         <span class="example-spacer"></span>
         <button mat-button>Create Incident </button>
         <a [routerLink]="['/closed']"><button mat-button style="color: white">Closed Incident</button></a>
        
         <span class="example-spacer"></span>
         <a [routerLink]="['/login']"><button mat-button>Logout</button></a>
         <img src="../../assets/hsbc_logo3.png" class="logo-hsbc"/>
        </mat-toolbar-row>
        <h1>INCIDENT MANAGEMENT SYSTEM</h1>

Answer 1

您需要移除

<h1>INCIDENT MANAGEMENT SYSTEM</h1>

或将其放入

 <mat-toolbar-row>

内。
