角度2 RC6-“侧边栏"不是一个已知的元素 [英] Angular 2 RC6 - "sidebar" is not a known element

问题描述

我刚刚更新到RC6，遇到以下错误:

I just updated to RC6 and have trouble with the following error:

zone.min.js:1未处理的承诺拒绝:模板解析错误: 侧边栏"不是已知元素: 1.如果侧边栏"是Angular组件，则确认它是该模块的一部分. 2.如果'sidebar'是Web组件，则将"CUSTOM_ELEMENTS_SCHEMA"添加到该组件的'@ NgModule.schema'以禁止显示此消息. ("

zone.min.js:1 Unhandled Promise rejection: Template parse errors: 'sidebar' is not a known element: 1. If 'sidebar' is an Angular component, then verify that it is part of this module. 2. If 'sidebar' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schema' of this component to suppress this message. ("

sidebar不是组件.我在一个模板中使用的只是一个html标签.他们看起来像这样:

sidebar isn't a component. Just a html-tag i am using in one of my templates. They look like this:

...
<sidebar class="main-nav">
    ...
</sidebar>
...

我尝试用CUSTOM_ELEMENTS_SCHEMA这样更新我的NgModule AppModule:

I tried updating my NgModule AppModule with CUSTOM_ELEMENTS_SCHEMA like this:

@NgModule({
    declarations: [...],
    providers: [...],
    imports: [BrowserModule, routing, HttpModule, FormsModule, TranslateModule.forRoot()],
    bootstrap: [AppComponent],
    schemas: [ CUSTOM_ELEMENTS_SCHEMA ]
})
export class AppModule { }

但这似乎无济于事.

有人没有想法或提示吗?

Does anyone haven an idea or a hint?

推荐答案

感谢 Pankaj Parkar 的评论

sidebar似乎尚未被接受.我必须实施变通方法.

sidebar seems not to to be accepted yet. I had to implement a workaround.

sidebar.directive.ts

import { Directive } from '@angular/core';

/**
 * dummy directive to allow html-tag "sidebar"
 */
@Directive({ selector: 'sidebar'})
export class SidebarDirective {}

将其包含在app.module.ts

Include it in app.module.ts

@NgModule({
    declarations: [..., SidebarDirective],
...
})
export class AppModule { }
