"Error: Arguments array must have arguments." AppModule

When running ng serve with a successful compilation in my Angular app, I started getting the following error in the browser console. 

AppComponent_Host.ngfactory.js? [sm]:1 ERROR Error: Arguments array must have arguments.

at injectArgs (core.js:1412)

at core.js:1491

at _callFactory (core.js:8438)

at _createProviderInstance (core.js:8396)

at resolveNgModuleDep (core.js:8371)

at NgModuleRef_.push../node_modules/@angular/core/fesm5/core.js.NgModuleRef_.get
(core.js:9064)

 at resolveDep (core.js:9429)

 at createClass (core.js:9309)

 at createDirectiveInstance (core.js:9186)

  at createViewNodes (core.js:10406)

This as far as I can tell from Main.ts platformBrowserDynamic().bootstrapModule(AppModule) .catch(err => console.log(err));

I have deleted the node modules folder and reinstalled and I'm having trouble with the lack of explanation the error gives. Plus, I'm somewhat new to Angular.

Any help would be greatly appreciated.

EDIT

I ran ng serve --aot and got the following error

First, try building/serving the app with ng serve --aot flag. Chances are some warning/error will be shown at the compile time.

As far as I can think, can you search in your project, if you are importing any component/module

like this import {something} from "../node_modules/@somepackage/adfas"; instead of import {something} from "@somepackage/adfas";

Also can you please share what you have in @NgModule({}) decorator, and in AppComponent constructor();

I think the angular is not able to provide all the injected dependencies.

I had same error, when @Injectable decorator and export keyword were not used for a dependency.

I made a typo instead of ":" I used "," in the constructor and had this error:

constructor(private myService, Myservice) {
}

//instead of

constructor(private myService: Myservice) {
}

I received this error due to having a circular dependency. I had a store which depended on some initial state which was provided by a service that depended on my store.

I resolved the issue by extracting the initial state, which was a constant object, to its own constants file.

I had the same error because of a circular dependency in my code:

Service1 > Service2 > Service1

This Typescript snippet demonstrates a scenario which causes this error.

...

export class AClassImportingAService {

    constructor(private _importedService) {
        // ERROR: notice there is no type on _importedService
        //   It should read 'private _importedService: ImportedService'
    }

...
}

In my case I was missing the injected type in the constructor :/
