javascript - Angular Material 2 工具提示问题

Question

我只是像这样将工具提示添加到 div 中:

<div  matTooltip="yeayh">
</div>

并将下面的 2 模块添加到父模块:

BrowserAnimationsModule,
MatTooltipModule,

工具提示显示没有问题，但我在浏览器控制台中得到了这个:

ERROR TypeError: Cannot read property 'matches' of null
    at Object.eval [as updateRenderer] (TooltipComponent.html:1)
    at Object.debugUpdateRenderer [as updateRenderer] (core.js:11087)

Answer 1

尝试更改“@angular/cdk”版本(例如“^6.0.0”)
