  <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
      - laravel/framework v4.2.1 requires php &gt;=5.4.0 -&gt; no matching package found.
      - laravel/framework v4.2.0 requires php &gt;=5.4.0 -&gt; no matching package found.
      - Installation request for laravel/framework 4.2.* -&gt; satisfiable by laravel/framework[v4.2.0, v4.2.1].
  
  Potential causes:
   - A typo in the package name
   - The package is not available in a stable-enough version according to your minimum-stability setting
