角2误差httpcliendmodule

Question

有一些误差httpclientmodule： 我有app.module.ts且有代码：

import { NgModule }  from '@angular/core'; 
import { BrowserModule } from '@angular/platform-browser'; 
import { FormsModule } from '@angular/forms'; 
import { AppComponent } from './app.component'; 
import {HttpClientModule } from '@angular/http'; 

@NgModule({ 
    imports:  [ BrowserModule, FormsModule, HttpClientModule ], 
    declarations: [ AppComponent ], 
    bootstrap: [ AppComponent ] 
}) 
export class AppModule { } 

和错误： nodemodules/@角/ HTTP/HTTP没有导出部件'HttpClientModule'

Answer 1

应该从@angular/common/http进口

import {HttpClientModule} from '@angular/common/http'; 

确保ÿ OU已经安装angular@^4.3.0（changelog）
