错误：找不到“ AppModule”的NgModule元数据。 在另一台机器上

Question

I try to deploy my Angular project on AWS S3 but i have this issue when try to ng build . However I have this issue only on server, but on local machine everything is fine.

All dependencies are same. I tried to reinstall and update angular-cli ; remove node modules and clean cache, but nothing happened. How to resolve this issue?

My full error is below:

 ERROR in Error: No NgModule metadata found for 'AppModule'.

here my app.module.ts :

import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { NgModule } from '@angular/core';
import { HttpClientModule, HttpClient } from '@angular/common/http';

import { AppComponent } from './app.component';

import { CoreModule } from './core/core.module';
import { LayoutModule } from './layout/layout.module';
import { SharedModule } from './shared/shared.module';
import { RoutesModule } from './routes/routes.module';
import 'hammerjs';
import { HttpModule } from '@angular/http';

@NgModule({
    declarations: [
        AppComponent,
    ],
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        CoreModule,
        LayoutModule,
        SharedModule.forRoot(),
        RoutesModule,
        HttpClientModule,
        HttpModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule { }

try doing some changes and compile again . It would compile successfully. Atleast for me it worked
