Cannot find the '@angular/common/http' module

Question

I am following this fundamental tutorial on Angular about Http.

As one can see in the "Setup: Installing the module" section, they import the HttpClientModule as follow:

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

When I try this in my project, I get the following error: "Cannot find module '@angular/common/http'".

I have tried importing the following module, as follow:

import { HttpModule } from '@angular/http'; 

And then my imports section:

imports: [     HttpModule ], 

The problem now is, I cannot inject this HttpModule into my service object, and I get the following error: "Cannot find module HttpModule".

Here is my service class:

import { Injectable, OnInit } from '@angular/core'; //Custom Models import { Feed } from '../Models/Feed';  @Injectable() export class FeedsService {     constructor(private httpClient: HttpModule) {} } 

What am I doing wrong?

Update All I should have done when I realized I could not import the module as per the tutorial, was to run the npm update command, to update all my packages.

Important: HttpClientModule is for Angular 4.3.0 and above. Check @Maximus' comments and @Pengyy's answer for more info.

Original answer:

You need to inject HttpClient in your component/service not the module. If you import HttpClientModule in your @NgModule

// app.module.ts:   import {NgModule} from '@angular/core'; import {BrowserModule} from '@angular/platform-browser';   // Import HttpClientModule from @angular/common/http import {HttpClientModule} from '@angular/common/http';   @NgModule({   imports: [     BrowserModule,     // Include it under 'imports' in your application module     // after BrowserModule.     HttpClientModule,   ], }) export class MyAppModule {} 

So change

constructor(private httpClient: HttpModule) {} 

to

constructor(private httpClient: HttpClient) {} 

as it's been written in the documentation

However, since you imported the HttpModule

you need to inject constructor(private httpClient: Http) as @Maximus stated in the comments and @Pengyy in this answer.
