【angular】Type Component is part of the declarations of 2 modules

Uncaught Error: Type **Component is part of the declarations of 2 modules Please consider moving **Component to a higher module that imports **Module and **Module. You can also create a new NgModule that exports and includes **Component then import that NgModule in **Module and **Module.

问题分析

一个组件在两个模块中定义，导致报错。

解决方案

将该组件定义到模块中，在其他模块中引用该模块。

如以下，将InfoComponent定义到InfoModule模块中：

import {NgModule}      from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {InfoComponent} from "../info/info.component";

@NgModule({
imports: [BrowserModule
],
exports:      [ InfoComponent ],
declarations: [InfoComponent]
})
export class InfoModule {

}

再将该模块引用到其他模块的imports数组中。
