Current behavior

J'ai pisté cette erreur et je me suis apperçu qu'elle était causé par le module de traduction, une fois ce code commenté tout va bien

TranslateModule.forRoot({
      loader: {
        provide: TranslateLoader,
        useFactory: (http: Http) => {
          return new TranslateHttpLoader(http);
        },
        deps: [Http]
      }
    }),

Voici l'erreur en détail, qui disparaît si je commente le code ci dessus, et que je relance le "ng serve"

Si je commente le code sans relancer le "ng serve" l'erreur devient celle-ci

This is not an error from the library but from your code.
useFactory requires an exported function, not an anonymous inline function.
Like explained in the documentation:

// AoT requires an exported function for factories
export function HttpLoaderFactory(http: Http) {
    return new TranslateHttpLoader(http);
}

@NgModule({
    imports: [
        BrowserModule,
        HttpModule,
        TranslateModule.forRoot({
            loader: {
                provide: TranslateLoader,
                useFactory: HttpLoaderFactory,
                deps: [Http]
            }
        })
    ],
    bootstrap: [AppComponent]
})
export class AppModule { }
