角2誤差httpcliendmodule

Question

有一些誤差httpclientmodule： 我有app.module.ts且有代碼：

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 { } 

和錯誤： nodemodules/@角/ HTTP/HTTP沒有導出部件'HttpClientModule'

Answer 1

應該從@angular/common/http進口

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

確保ÿ OU已經安裝angular@^4.3.0（changelog）

又見文檔
