我刚从Angular 2 rc4升级到rc6,在这方面遇到了麻烦.
我在控制台上看到以下错误:
Unhandled Promise rejection: Template parse errors:
'cl-header' is not a known element:
1. If 'cl-header' is an Angular component, then verify that it is part of this module.
2. If 'cl-header' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schema' of this component to suppress this message. ("<main>
[ERROR ->]<cl-header>Loading Header...</cl-header>
<div class="container-fluid">
<cl-feedbackcontai"): AppComponent@1:4
下面是我的页眉组件:
import { Component } from '@angular/core';
import { Router } from '@angular/router';
// own service
import { AuthenticationService } from '../../../services/authentication/authentication.service.ts';
import '../../../../../public/css/styles.css';
@Component({
selector: 'cl-header',
templateUrl: './header.component.html',
styleUrls: ['./header.component.css']
})
export class HeaderComponent { // more code here... }
这是我的页眉模块:
import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { RouterModule } from '@angular/router';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { HeaderComponent } from './../../../components/util_components/header/header.component.ts';
@NgModule({
declarations: [ HeaderComponent ],
bootstrap: [ HeaderComponent ],
imports: [ RouterModule, CommonModule, FormsModule ],
schemas: [ CUSTOM_ELEMENTS_SCHEMA ]
})
export class HeaderModule { }
我创建了一个名为util module的包装器模块,该模块导入HeaderModule:
import { NgModule } from '@angular/core';
import {HeaderModule} from "./header/header.module";
// ...
@NgModule({
declarations: [ ],
bootstrap: [ ],
imports: [ HeaderModule]
})
export class UtilModule { }
最终由AppModule导入:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import {UtilModule} from "./modules/util_modules/util.module";
import {RoutingModule} from "./modules/routing_modules/routing.module";
@NgModule({
bootstrap: [AppComponent],
declarations: [AppComponent],
imports: [BrowserModule, UtilModule, RoutingModule]
})
export class AppModule { }
据我所知,我是在遵循错误消息的说明,使用模式来 suppress 错误.但这似乎并不管用. 我做错了什么? (我希望这不是什么明显的事情,只是我现在看不到.在过go 的6个小时内一直在升级到此版本.)
