title: Typescript Node.js simplest setup doesn't work -- error TS2307: Cannot find module 'fs'
body: <p>I've installed TS and the node typings globally:</p>
  
  <pre><code>PS C:\Projects\Test&gt; npm list --global --depth=0
  C:\Users\Jan\AppData\Roaming\npm
  +-- @types/node@7.0.5
  +-- tslint@4.4.2
  `-- typescript@2.2.1
  </code></pre>
  
  <p>Then I've created a file test.ts</p>
  
  <pre><code>import fs = require("fs");
  let text = fs.readFileSync("myFile.txt");
  console.log(text);
  </code></pre>
  
  <p>Runnning tsc results in</p>
  
  <pre><code>PS C:\Projects\Test&gt; tsc .\test.ts
  test.ts(1,21): error TS2307: Cannot find module 'fs'.
  </code></pre>
  
  <p>Do I miss something obvious?</p>
  
  <p>Thanks!</p>
