我有一个声明了几个组件的模块,当我在模板中使用指令语法时,角度找不到组件 - 我收到此错误
'test-cell-map' is not a known element:
这是组件模块
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AppComponent } from './app.component';
import { TestCellMapComponent } from './test-cell-map/test-cell-map.component';
@NgModule({
declarations: [
AppComponent,
TestCellMapComponent
],
imports: [
BrowserModule,
FormsModule,
HttpModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
这是顶级组件的样子
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'app works!';
}
及其相关模板
<h1>
{{title}}
<test-cell-map></test-cell-map>
</h1>
答案 0 :(得分:1)
你有 TestCellMapComponent 选择器
的问题<h1>
{{title}}
<app-test-cell-map></app-test-cell-map> //<<<<===== changed
</h1>
