Angular2 / Nativescript：嵌套StackLayouts时出现奇怪的“意外标记”错误-Java 学习之路

我正忙着一个Angular2 Nativescript应用程序，它之前工作得非常好，但是在将输入字段移动到我视图的另一部分后，我得到以下错误，说出意外的结束标记“StackLayout”...任何想法可能导致这种情况？可以嵌套在彼此内的堆栈布局数量是否有限制？我移动到视图的不同部分的输入字段是qty输入字段...

我得到的错误：

这是你的问题：
```
<StackLayout class="input-field">
       <TextField class="input input-border" hint="Enter Quantity" keyboardType="number" [(ngModel)]="qty">
 </StackLayout>
```
你忘了关闭 </TextField> 下一个结束标记是 /StackLayout 它正在抛出错误，因为它与之前的 TextField 不匹配 .

我得到了相同的错误，这个以下行导致错误时使用字体真棒
```
nt-awesome" text="&#xf1f8;
```
并尝试使用以下方法解决它：fonticon-nativescript angular
