title: How does one install an older version of TypeScript on mac os x?
body: <p>I am using WebStorm on a mac for development, and the latest stable release only supports 0.8.x version of TypeScript while npm installs 0.9.x, creating various conflicts with IDE.</p>
  
  <p>Currently npm will install 0.9.x version with:</p>
  
  <pre><code>npm install -g typescript
  </code></pre>
  
  <p>how can I force it to install older version of TypeScript compiler?</p>
