没有导出成员'DROPDOWN_DIRECTIVES'

Question

我在angular2应用中安装了'ng2-dropdown'。它给

error: [ts] Module "has no exported member 'DROPDOWN_DIRECTIVES'. import DROPDOWN_DIRECTIVES". 

，当我在组件进口DROPDOWN_DIRECTIVES作为

import {DROPDOWN_DIRECTIVES} from "ng2-dropdown"; 

我已经做 'NPM安装NG2-下拉'

Answer 1

按RC6发布directives已被弃用的Component元。你必须导入DropdownModule模块在AppModule元数据的声明一样simple example

Answer 2

尝试使用@ngModule这样

import {Component, NgModule} from "@angular/core"; 
import {platformBrowserDynamic} from "@angular/platform-browser-dynamic"; 

@NgModule({ 
    imports: [ 
     LIST_OF_IMPORTS_HERE..., 
     DropdownModule, 
     ..... 
    ], 
    declarations: [ 
     MAIN_FILE_HERE 
    ], 
    bootstrap: [ 
     MAIN_FILE_HERE 
    ] 
}) 

export class ModuleApp { } 

platformBrowserDynamic().bootstrapModule(ModuleApp); 

请看changelog为RC6这里https://github.com/angular/angular/commit/4a740f2

你要名单下跌导入所有的指令和管道，而不是最新版本的组件级别。
