即使包含类型文件，Typescript也会抛出属性上不存在的属性

Question

I'm using TypeScript with webpack and ES6. I'm trying to import the module Showdown and use it to convert markdown to HTML. Here's my app.ts code:

/// <reference path="../typings/tsd.d.ts" />

import 'zone.js';
import 'reflect-metadata';
import 'es6-shim';

import * as showdown from 'showdown';

import {Component, View, bootstrap} from 'angular2/angular2';

@Component({
  selector: 'markdown-app'
})
@View({
  templateUrl: '/app/markdownApp.html'
})
class MarkdownAppComponent {
  public html: string;
  private md: any;

  constructor() {
    this.html = '';
    this.md = showdown.Converter();
  }

  public updateValue(val) {
    this.html = this.md.makeHtml(val);
  }
}

bootstrap(MarkdownAppComponent);

When I try to convert TS to ES6, I get the following error:

ERROR in ./src/app/app.ts
(23,24): error TS2339: Property 'Converter' does not exist on type 'typeof Showdown'.

I'm using TSD to install all of the type definitions. Angular loads up fine but Showdown seems to be having trouble. The Showdown type file seems to be correct (including the property Converter) and from what I can understand, it loads up fine.

I console logged out the showdown variable to make sure that Showdown did indeed get importer and it did, and it has the Converter property.

Any ideas?

I ran into a similar issue and I had to do:

this.md = new showdown.Converter();

instead of

this.md = showdown.Converter();

Looks like you solved your problem a while ago, but in case anyone runs into this issue I figured I'd throw my solution up here.
