Importing both HttpModule and HttpClientModule fixes the problem.

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

[vicb]

@ocombe is working on a fix (better error message)

[SK-Agrawal]

Add import { HttpModule } from '@angular/http'; in app.module.ts

[Heena-Vora]

still not working for me

[raghavjatin]

also not working for me , same error

[Moshiour027]

same here

[Muhammad-Soban]

Not working for me

[crowster]

in app module Step 1 add import import { HttpModule } from '@angular/http'; Step 2 add HttModule in : imports: [ HttpModule
], .....

Maybe you need to add in the service import { Http ,HttpModule} from '@angular/http' too

[RyannGalea]

Have the same issue :(

[danielszuk]

same issue here (ive imported the httpmodule, but still not working)

[jersonjohn]

Same error , Not working for me too

[mumairofficial]

Worked by importing HttpClientModule even I am not using this module in whole app.. that's wired.

[jersonjohn]

Have to add app.module.ts under provider section to make them available in providers

Problem fixed!! HUHU

[ilivestrong]

@jersonjohn - Which service to registere in Providers section. I am facing the same issue and after reading above suggestions, I have already imported HttpClient and HttpClientModule in my app.module.ts (even though I am not using them)...

Please advise.

Thanks Deepak

[ilivestrong]

[jersonjohn]

providers: [ AuthGuard, CookieService, CompanyService, PolicyService, CommunicationService, AuthenticationService ]

[jersonjohn]

@ilivestrong all services need to configure in the providers section of the app.module.ts

Something like this

providers: [ AuthGuard, CookieService, CompanyService, PolicyService, CommunicationService, AuthenticationService ]

[ilivestrong]

@jersonjohn - I already have all my custom services and angular services in providers array. Not sure why it's not working. I am just trying to build a login page using a reactive form (using FormBuilder).

Not sure what is breaking it...

[mumairofficial]

@ilivestrong have you included ReactiveFromsModule in import array of app.module.ts

[ilivestrong]

@mumairofficial - Yes I did. Strangely I created a new project and it went away, only until I wrote a new route guard and I get this StaticInjectionError for my route guard now.

This route guard is provided as well. :(

[HanVertegaal]

I had the same problem after creating a new service using ng-cli. This should automatically add the service to the providers array in app.module.ts

[VikashChoudahry]

I had same issue but after importing "HttpModule" in "app.module.ts" it worked fine for me.

1. import { HttpModule } from '@angular/http';
2. Add "HttpModule" in imports array list.

Thanks. Keep Sharing.

[ShahidMirza2017]

Add import { HttpModule } from '@angular/http'; in app.module.ts for Http Or Add import {HttpClientModule} from '@angular/common/http' in app.module.ts for httpclient

[amitkprajapati]

I imported both HttpModule and HttpClientModule but still getting the same error , Please any one help me out , i am trying to implement routing .

[nvigneux]

@amitkprajapati import HttpClientModule in app.module.ts

import { HttpClientModule } from '@angular/common/http'
///
@NgModule({
  imports: [ HttpClientModule ]
})

[HolyMarsia]

I had the same problem. in my app this issue I did it like this. step1. Check. app.Module.ts file inner import []

step2. Check the modules you created and see if any of the newly created files are unimported.

• In my case, I tried to register with the ' Effect ' without importing ' FreezerService ' from the 'core module' that manages the service module.

[mumairofficial]

add FreezerService into providers array of app.module.ts

[EmRa228]

Stop ionic and rerun "ionic serve" to show real error message to you.

[mamad1295]

@ilivestrong I got the same. Adding providers: [UserService] in my userListComponent fixed it.

@Component({
  selector: 'app-user-list',
  templateUrl: './user-list.component.html',
  styleUrls: ['./user-list.component.css'],
  providers: [UserService]
})

This component is imported by my user-module which itself is imported in app-module.

Hope it helps !

[kverma17]

Not working with any of the solutions.

@kverma17 add Camera to provider array in side of app.module.ts and donot forget to import it :)

I am not sure camera will work properly in browser but the error you have posted will go away.

You need provide your dataservices import ........... import { DataService } from '../dataservice';

@Component({ selector: '....... templateUrl: ........ styleUrls:......, providers: [DataService] })

[miriiit]

these error occur when we use feature module just add

RouterModule.forRoot({}) above the RouterModule.forFeature('Items',reducers)

[nagarajbyndoor]

Thanks @jersonjohn your suggestions helped :)

[csharpspecialist]

Make sure you are adding HttpModule and not just Http. That was my problem. Even adding Http would not fix my issue. I had to add HttpModule as shown in the next paragraph.

Add import { HttpModule } from '@angular/http'; in app.module.ts , which of course means that I had to add it to the imports array below as well.

If you Add import { Http } from '@angular/http'; in app.module.ts by itself then it will still show you an error...even if you add a reference to it in the imports array/list below.

The newest version of the CLI does not add this to your build when using npm if it is generating a new package for some reason. It must have previously done this but not any longer.

If you are trying to build this youtube series project then you will need to import HttpModule into your app.module.ts file!!! https://www.youtube.com/watch?v=pxv-0WeT44w

[mumairofficial]

Just for information ~HttpModule~ is deprecated in favor of HttpClientModule from @angular/common/http package; use the latest one to make upgrade easy :+1:

[byassine52]

I had the same problem when I moved a property to a component inside constructor() parameters. It was solved when I moved it out back.

[garycsebastian]

ionic serve ... again

[disujha]

Apart from above solutions... I think removing the NavCtrl from service also helps. Seems there is conflict between NavCtrl of Component and Service/Provider

[noameini]

[geyma1311]

my solution was to add my service in the providers in my component.ts

[chambahr]

import { HttpModule } from '@angular/http'; and then add HttpModule to imports

,imports: [ HttpModule, BrowserModule, IonicModule.forRoot(MyApp), ], This fixes the problem for me. you can also import import { HttpClientModule } from '@angular/common/http'; for convenience sake

[fmorc]

You need to provide your service in the module where your component is being declared:

@NgModule({ imports: [ SharedModule, RouterModule.forChild([ { path: 'login', component: LoginComponent } ]) ], declarations: [ LoginComponent ], providers: [ AuthService ]

And then referencing it in your component and injecting in the constructor. Make sure your service has the Injectable decorator

[duggu123]

Uncaught in promise error occurs when you did not import required dependency . I got error of Error: Uncaught (in promise): Error: StaticInjectorError[AngularFireAuth] so I import AngularFireDatabaseModule <---- for database AngularFireAuthModule <----for AngularAuth

import { AngularFireModule } from 'angularfire2'; // for AngularFireDatabase import { AngularFireDatabaseModule } from 'angularfire2/database'; import { AngularFireDatabase, FirebaseObjectObservable } from 'angularfire2/database'; // for AngularFireAuth import { AngularFireAuthModule } from 'angularfire2/auth'; import { AngularFireAuth } from 'angularfire2/auth';

@NgModule({ imports: [ AngularFireModule.initializeApp({
authDomain: '...', databaseURL: '...', storageBucket: '...', messagingSenderId: '...' }),
AngularFireDatabaseModule,
AngularFireAuthModule
] })

[T-candy]

i solved this problem. at 'app.module.ts' add

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

and, imports: [ BrowserModule, HttpModule, HttpClientModule, IonicModule.forRoot(MyApp) ]

[qam12]

Thanks @mushinz

[ProgrammingFuad]

@jersonjohn thanks your guidance on adding services as a provider did the trick for me!

[SadmiB]

I got this error in Angular 5.2.7 and importing HttpClientModule to the app.module.ts solved the the problem, don't forget to add HttpClientModule to the imports: [] and don't forget the service provider too providers: []
