title: "Composer update for Laravel: Requirements could not be resolved to an installable set of packages."
body: <p>I recently tried updating my laravel project using composer, using this in the requirements section:</p>
  
  <pre><code>"require": {
  
      "laravel/framework": "4.0.*",
  
          "way/generators": "dev-master",
  
          "taylorotwell/laravel-oauth2": "0.2.*",
  
          "juy/profiler" : "dev-master", 
  
          "cviebrock/eloquent-sluggable": "1.0.*"
  
      },
  </code></pre>
  
  <p>I received the following error:</p>
  
  <pre><code>Loading composer repositories with package information
  
  Updating dependencies (including require-dev)
  
  Your requirements could not be resolved to an installable set of packages.

  <p>I've never seen this before.  I tried removing the <code>"cviebrock/eloquent-sluggable": "1.0.*"</code> line (because it was recently added), but I am seeing the same error.  Any ideas?  Thank you.  </p>
