title: installing laravel via composer InvalidArgumentException
body: <p>I want to install laravel 4.x and as you know I <b>must</b> use composer.<br/>
  I've tried:<br>
  <code>composer create-project laravel/laravel d:\xampp\htdocs\laravel</code><br></p>
  
  <pre><code>  [InvalidArgumentException]
    Could not find package laravel/laravel with stability stable.

  </code></pre>
  
  <p>I've downloaded laravel from <a href="https://github.com/laravel/laravel" rel="nofollow">github repo</a> and then tried this one:<br>
  <code>composer install</code><br>
  and this time I got:</p>
  
  <pre><code>Loading composer repositories with package information
  Installing dependencies (including require-dev)
  Your requirements could not be resolved to an installable set of packages.
  
    Problem 1
      - The requested package laravel/framework could not be found in any version, there may be a typo in the package name.
  
  Potential causes:
   - A typo in the package name
   - The package is not available in a stable-enough version according to your minimum-stability setting
