Question

HI im使用Angular 6和ng-boostrap我添加了一个模态调用FocusComponent，我需要将其添加到entryComponents，因此我将ConfirmAutoFocusComponent添加到app.module.ts中，如下所示：

bootstrap: [AppComponent, ConfirmAutoFocusComponent]

它可以工作，但是在F12控制台上弹出错误

ERROR Error: The selector "app-confirm-auto-focus" did not match any elements

我看到了有关此问题的其他帖子，但是它的作用似乎很有效

更多@ user184994和@CruelEngine 将其添加到app.module.ts中

 bootstrap: [AppComponent], entryComponents: [ConfirmAutoFocusComponent]

解决了问题

选择器“ app-confirm-auto-focus”与任何元素都不匹配
