Uncaught (in promise): Error: StaticInjectorError(

问题:

I have a strange error. Usually (I did my googling), in this case of errors Angular specifies in square brackets which exactly module/service/provider/etc caused the problem. However here, it says only options.

I tried adding HttpClientModule, HttpModule, Options to providers/imports - no success.

Tried to follow this debugging guide Debugging Unknown provider in minified angular javascript but also it brought me to nothing (no invoke on the call stack, just invokes associated with Zone)

my app.components.ts looks like this:

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `<router-outlet></router-outlet>`,
})
export class AppComponent {
  constructor() {}
}

When I go into debugging mode the last function calling the error is :

function defaultErrorLogger(console) {
    var values = [];
    for (var _i = 1; _i < arguments.length; _i++) {
        values[_i - 1] = arguments[_i];
    }
    console.error.apply(console, values);
}

回答1:

Here is what worked for me (Angular 7):

First import HttpClientModule in your app.module.ts if you didn't:

import { HttpClientModule } from '@angular/common/http';
...
imports: [
        HttpClientModule
    ],

Then change your service

@Injectable()
export class FooService {

to

@Injectable({
    providedIn: 'root'
})
export class FooService {

Hope it helps.

回答2:

It also might be that you haven't declared you Dependency Injected service, as a provider in the component that you injected it to. That was my case :)

回答3:

I was having the same problem using my class SharedModule.

export class SharedModule {
    static forRoot(): ModuleWithProviders {
        return {
            ngModule: SharedModule,
            providers: [MyService]
         }
     }
}

Then I changed it putting directly in the app.modules this way

@NgModule({declarations: [
AppComponent,
NaviComponent],imports: [BrowserModule,RouterModule.forRoot(ROUTES),providers: [MoviesService],bootstrap: [MyService] })

Obs: I'm using "@angular/core": "^6.0.2".

I hope its help you.

回答4:

I had the same error and I solved it by importing HttpModule in app.module.ts

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

and then in the imports[] array:

HttpModule

回答5:

If we need to move from one component to another service then we have to define that service into app.module providers array.

回答6:

Faced the same error. In my case , what i did wrong was that i injected the service(named DataService in my case) inside the constructor within the Component but I simply forgot to import it within the component.

 constructor(private dataService:DataService ) {
    console.log("constructor called");
  }

I missed the below import code.

import { DataService } from '../../services/data.service';

回答7:

HttpClientModule needs to be in the imports array, and remove it from providers. That section is for you to tell Angular which services the module has (written by you and not imported from a library).

回答8:

In my case, the error was in using angular2-notifications 0.9.8 instead of 0.9.7
