Angular2/Nativescript：嵌套 StackLayout 时出现奇怪的"Unexpected tag"错误

Question

我正在忙于一个angular2 nativecript应用程序，该应用程序在之前效果很好，但是在将输入字段移至视图的另一部分之后，我会遇到以下错误，说明意外关闭标签" stacklayout"。。可以彼此嵌套的堆栈布局数量有限制吗？我移至视图的另一部分的输入字段是数量输入字段...

我遇到的错误：

Answer 1

这是您的问题：

 <StackLayout class="input-field">
       <TextField class="input input-border" hint="Enter Quantity" keyboardType="number" [(ngModel)]="qty">
 </StackLayout>  

您忘记了关闭的</TextField>下一个关闭标签是/StackLayout，它在其上丢失了错误，因为它在其之前与TextField不匹配。

Answer 2

我得到了相同的错误旅馆，以下行会导致使用字体棒极了

nt-awesome" text="

尝试使用：Fonticon-NativeScript Angular
