Answer 1

Add HttpClientModule in your app.module.ts and try, it will work so sure. for example

import { HttpModule } from '@angular/http

Answer 2

Make sure you have imported HttpClientModule instead of adding HttpClient direcly to the list of providers.

See https://angular.io/guide/http#setup for more info.

The HttpClientModule actually provides HttpClient for you. See https://angular.io/api/common/http/HttpClientModule:

Code sample:

import { HttpClientModule, /* other http imports */ } from "@angular/common/http";

@NgModule({
    // ...other declarations, providers, entryComponents, etc.
    imports: [
        HttpClientModule,
        // ...some other imports
    ],
})
export class AppModule { }

Answer 3

import the HttpClientModule in your app.module.ts

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

...
@NgModule({
...
  imports: [
    //other content,
    HttpClientModule
  ]
})
