How to solve the "module has no exported member" error?

Question

I am following instructions from the this answer, but cannot make the solution work.

Overview

I want to use import { Type } from "Module" instead of /// <reference path="..." />

Structure

-app\   -ViewModel.ts   -Program.ts 

ViewModel.ts

export module Demo {     export class ViewModel {         constructor(public test: string) {         }     } } 

Program.ts

import { ViewModel } from "ViewModel"; 

Module 'C:/DemoApp/app/ViewModel' has no exported member 'ViewModel'.

and...

Only 'amd' and 'system' modules are supported alongside --outFile.

Goal

I want to be able to reference dependencies so that they compile to a single file in order.

---

If I add "module": "system" I still get the 1st of the aforementioned errors.

As per the 1st solution, I do not want to lose namespaces.

Answer 1

Remove the line below from your statement

export module Demo 

and use it like

export class ViewModel {     constructor(public test: string) {     } } 

Edit: For namespace, just do something like

namespace Demo {   export class ViewModel {         constructor(public test: string) {         }     } }
