我在材料设计的官方文档方面遇到了一些问题， 他们说

可以使用 disabled 属性禁用扩展面板。用户无法切换禁用的扩展面板，但仍可以通过编程方式进行操作。

  
    This is the expansion title
  
  
    This is a summary of the content
  

但是当我尝试它时会抛出一些错误-

Uncaught Error: Template parse errors:
Can't bind to 'disabled' since it isn't a known property of 'md-expansion-panel'.
1. If 'md-expansion-panel' is an Angular component and it has 'disabled' input, then verify that it is part of this module.
2. If 'md-expansion-panel' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("

            ][disabled]="true"

               routerLink="/settings/tools"
")

有什么帮助吗？
