Node.js 分析模板时出错：意外关闭标记应用程序帖子列表

当我试图以角度输出帖子时出错。请帮助解决此问题

错误消息

import { Component } from "@angular/core";

@Component({
selector: 'aap-post-list',
templateUrl: './post-list.component.html'
})

export class PostListComponent {}

<app-header></app-header>
<main>
  <app-post-create></app-post-create>
  <aap-post-list></app-post-list>
</main>

分析模板时出错：意外的结束标记“应用程序帖子列表”

我的post-list.component.ts代码

import { Component } from "@angular/core";

@Component({
selector: 'aap-post-list',
templateUrl: './post-list.component.html'
})

export class PostListComponent {}

<app-header></app-header>
<main>
  <app-post-create></app-post-create>
  <aap-post-list></app-post-list>
</main>

我的帖子列表.component.html

<mat-accordion>
   <mat-expansion-panel>
    <mat-expansion-panel-header>
      The expansion title!
    </mat-expansion-panel-header>
    <p>I'm in an expansion panel!</p>
   </mat-expansion-panel>
</mat-accordion>

请让我知道我错在哪里，以及我如何解决这个问题

您好，您在行号4中输入了错别字，将

更改为

问题已解决

app.component.html代码

<app-header></app-header>
<main>
  <app-post-create></app-post-create>
  <aap-post-list></app-post-list>
</main>

现在将选择器更改为

从“@angular/core”导入{Component}”

到

从“@angular/core”导入{Component}”

现在它应该可以正常工作了

这是一个打字错误。在app.component.html中，将

替换为

。更好的是，将组件选择器更改为

应用程序帖子列表

。如果问题已解决，请单击回答上的已解决图标现在我收到此错误消息src/app/app.component.html:4:5-错误NG8001:“应用程序帖子列表”不是已知元素：如果“应用程序帖子列表”是角度组件，请验证它是否是此模块的一部分。如果“app post list”是一个Web组件，则将“CUSTOM_ELEMENTS_SCHEMA”添加到此组件的“@NgModule.schemas”以抑制此消息。src/app/app.component.ts:5:16 templateUrl:“./app.component.html”，组件AppComponent的模板中出现错误。先生，谢谢您的回答，我更改了它，但现在我收到以下消息：如果“app post list”是角度组件，则“app post list”不是已知元素，然后验证它是否是此模块的一部分。如果“app post list”是Web组件，则将“CUSTOM_ELEMENTS_SCHEMA”添加到此组件的“@NgModule.schemas”以抑制此消息。您已将该组件声明为

aap post list

。所以你也应该更改声明（选择器）。将选择器：“aap帖子列表”更改为“应用帖子列表”@NaveenKumar抱歉，我没有得到你的答案，请解释me@ayushflitzip现在检查我的答案

@Component({
selector: 'app-post-list',
templateUrl: './post-list.component.html'
})

export class PostListComponent {}
