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  And for more info on differences between HttpModule and HttpClientModule  check this answer
