title: Typescript unable to find Express module
body: <p>I am trying to create my first NodeJS application, however I couldn't make it work.</p>
  
  <p>These are the steps I followed so far from various blogs and trying to build first nodejs app in typescript.</p>
  
  <pre><code>npm install -g express-generator
  npm install -g typescript
  express SampleApp
  npm install -g typings
  typings install dt~node --global
  typings install dt~express dt~serve-static dt~express-serve-static-core --global
  cd SampleApp
  npm install
  </code></pre>
  
  <p>hello.ts</p>
  
  <pre><code>import express = require('express');
  var app = express();
  </code></pre>
  
  <p>When I build compile the ts file with TypeScript </p>
  
  <pre><code>&gt;&gt;&gt; tsc -m commonjs -t es5 hello.ts
  hello.ts(1,26): error TS2307: Cannot find module 'express'.
  </code></pre>
  
  <p>I have gone through various resources, couldn't find the solution.
  I guess I don't have to copy node.d.ts and express.d.ts files manually to the project folder.</p>
  
  <p>If I use nodejs and expressjs alone <code>npm start</code> it works fine. <code>Typescript</code> plugin is something I am not able to do </p>
  
  <p>Can anyone help what exactly I am doing wrong here?</p>
