Question

我正在开发一个angular2项目和primeng，我的问题是当我使用它时，primeng中的树给了我错误。我执行了npm install primeng --save 我导入了import {TreeModule,TreeNode} from 'primeng/primeng'; 当我输入<p-tree></p-tree>时会出现以下错误：

NodeInvocationException：模板解析错误：无法绑定到'value' 因为它不是'p-tree'的已知属性。 1.如果'p-tree'是一个Angular组件并且它有'value'输入，那么请确认它是该模块的一部分。

这是我的NgModule：app.module.shared.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import {FormsModule, NgModel, ReactiveFormsModule} from '@angular/forms';
import { RouterModule } from '@angular/router';

import { AppComponent } from './components/app/app.component';

import {EditCustomerComponent} from "./components/Customer/edit_add_customer/edit_cusotmer.component";
import {ProductTreeComponent} from "./components/Product/products_tree/product_tree.component";
import {TreeModule ,SharedModule } from 'primeng/primeng';


@NgModule({
    declarations: [
        AppComponent,
        NavMenuComponent,
        FetchDataComponent,
        HomeComponent,

    imports: [
        CommonModule,

        TreeModule,
        SharedModule,
        RouterModule.forRoot([
            { path: 'home', component: HomeComponent },
            { path: 'users', component: UsersComponent },
            { path : 'user', component: UserComponent },
            { path : 'login', component: LoginComponent },
            { path : 'adduser', component: AddUserComponent },

            { path : 'products_tree', component: ProductTreeComponent}





            //{ path: '**', redirectTo: 'home' }
        ], { useHash: true })
    ], 
    providers : [

        StorageService,
        ProductsService,
        { provide : HTTP_INTERCEPTORS , useClass : AuthInterceptorService, multi: true}
        ]
})


export class AppModuleShared {
}

Answer 1

在app.module.ts中添加相同内容

import {TreeModule} from 'primeng/primeng';

@NgModule({
    imports:      [
        TreeModule,
],
});

树在primeng的angular2
