Angular 7 并且无法绑定到 'routerlink'，因为它不是 'a' 的已知 属性
Angular 7 and can't bind to 'routerlink' since it isn't a known property of 'a'
我正在创建一个新的 Angular 7 应用程序，过去几天我一直在研究这个问题，但我找不到解决这个错误的方法：

布局如下：

我不知道问题出在哪里。据我所知，我有适当的进出口。如果您看到我看不到的内容，请随时发表评论。
如果您需要更多信息，例如更多代码，也请告诉我。
属性routerLink区分大小写。
change [routerlink] to [routerLink]
[routerLink]="['/vendors']"
我有类似的错误"Can't bind to 'routerlink' since it isn't a known property of 'button' "。
将模块 RouterTestingModule.withRoutes([]) 添加到规范 class 解决了我的问题。
对于那些 routerLink 驼峰式大小写正确但仍然遇到相同错误的人，您可能没有在定义组件的模块中导入 RouterModule。
