离子3模块声明错误

Question

运行命令下面的工作原理： ionic cordova build ios

但在以下错误

Error: Type ExpandableHeaderComponent in /Users/jobstore/jobstore/js/src/components/expandable-header/expandable-header.ts is part of the declarations of 2 modules: SharedModuleComponent in /Users/jobstore/jobstore/js/src/components/shared-module/shared-module.ts and ExpandableHeaderComponentModule in /Users/jobstore/jobstore/js/src/components/expandable-header/expandable-header.module.ts! Please consider moving ExpandableHeaderComponent in /Users/jobstore/jobstore/js/src/components/expandable-header/expandable-header.ts to a higher module that imports SharedModuleComponent in /Users/jobstore/jobstore/js/src/components/shared-module/shared-module.ts and ExpandableHeaderComponentModule in /Users/jobstore/jobstore/js/src/components/expandable-header/expandable-header.module.ts. You can also create a new NgModule that exports and includes ExpandableHeaderComponent in /Users/jobstore/jobstore/js/src/components/expandable-header/expandable-header.ts then import that NgModule in SharedModuleComponent in /Users/jobstore/jobstore/js/src/components/shared-module/shared-module.ts and ExpandableHeaderComponentModule in /Users/jobstore/jobstore/js/src/components/expandable-header/expandable-header.module.ts.

我试图创建共享模块运行以下

ionic cordova build ios --prod 

结果：

import { Component ,NgModule} from '@angular/core'; 
import {ExpandableHeaderComponent} from '../expandable-header/expandable-header'; 
import {ShrinkHeaderComponent} from '../shrink-header/shrink-header'; 


@Component({ 
    selector: 'shared-module', 
    templateUrl: 'shared-module.html' 
}) 



@NgModule({ 
    declarations: [ 
    ExpandableHeaderComponent, 
    ShrinkHeaderComponent 

    ], 

    exports: [ 
    ExpandableHeaderComponent, 
    ShrinkHeaderComponent 
    ] 

}) 

export class SharedModuleComponent { 

    constructor() { 
    } 

} 

和app.module.ts

其导入

这里

import { SharedModuleComponent } from '../components/shared-module/shared-module'; 

这里

 imports: [ 
    BrowserModule, 
    HttpModule, 
    SharedModuleComponent, 
    ], 

，但我仍然面临着同样的问题。

的这个错误告诉你需要做什么。除此之外，我注意到您为ExpandableHeaderComponent创建了另一个模块。如果你不懒惰加载你的模块，最好只是在你的SharedModule或直接对你的AppModule
