我想使用带有电容相机插件的原生相机。但是在实施之后，我无法再打开页面（当我单击将我路由到该页面的按钮时没有任何反应）我发现错误必须在注释的 html 部分中。但它没有显示错误。当该部分没有评论时，整个应用程序会加载。
page.html
<ion-content>
<!--
<ion-card>
<img
role="button"
class="image"
(click)="onPickImage"
[src]="selectedImage"
*ngIf="selectedImage"
>
</ion-img>
</ion-card>
-->
<ion-footer>
<ion-button (click)="onPickImage()" *ngIf="!selectedImage" class="buttonPost" expand="full" color="primary">Take Photo</ion-button>
</ion-footer>
