I want to create Angular application without CLI.
After that I get an error:

Error: Can't resolve all parameters for ApplicationModule: (?).

Project contains couple files, main of this is:

• main.ts

import 'zone.js/dist/zone'

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './modules/app.module';



platformBrowserDynamic().bootstrapModule(AppModule)

• component.ts

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



@Component({

    selector: 'app-root',

    template: `Hello World`

})

export class AppComponent {}

• module.ts

import { NgModule } from "@angular/core";

import { BrowserModule } from "@angular/platform-browser";

import { AppComponent } from "../components/app.component";



@NgModule({

    imports: [

        BrowserModule,

    ],

    declarations: [

        AppComponent

    ],

    bootstrap: [

        AppComponent

    ]

})

export class AppModule {}

I search on StackOverflow before, but I can't found solution.
Similar error occur when someone wants to inject service without @Injectable decorator. In my case I don't have any service, so that am afraid nobody has the same error.

Angular CLI is so simple to start project, but only when you want setup project without generator, you know what parts are necessary to create during bootstrap application.

1. 
   

   Install core-js by command:

   
   
   

   npm i core-js
   
   

   
   


2. 
   

   Add in main.ts file:

   
   
   

   import 'core-js/es6/reflect';
   
   import 'core-js/es7/reflect';
   
   

   
   

Btw. I'm spent whole day to resolve this.
