title: composer can only install one of: symfony/console
body: <p>I'm trying to upgrade from laravel 5.1 to 5.3.  When attempting to run composer update, it's failing saying that I'm trying to install multiple versions of symfony/console.  Part of the error is below </p>
  
  <pre><code>Can only install one of: symfony/console[v3.1.0-BETA1, v2.8.9].
  - Can only install one of: symfony/console[v3.1.0-BETA1, 2.7.x-dev].
  - laravel/framework v5.3.0-RC1 requires symfony/console 3.1.* -&gt; satisfiable by symfony/console[3.1.x-dev, v3.1.0, v3.1.0-BETA1, v3.1.0-RC1, v3.1.1, v3.1.10, v3.1.2, v3.1.3, v3.1.4, v3.1.5, v3.1.6, v3.1.7, v3.1.8, v3.1.9].
  - Conclusion: don't install peridot-php/peridot 1.16.0|don't install symfony/console 3.1.x-dev
  - Conclusion: don't install peridot-php/peridot 1.16.0|don't install symfony/console v3.1.10
  peridot-php/peridot 1.16.0 requires symfony/console ~2.0 -&gt; satisfiable by symfony/console[2.7.x-dev, 2.0.4, 2.0.5, 2.0.6, 2.0.7, 2.0.x-dev
  </code></pre>
  
  <p>laravel 5.3 requires symfony/console 3.1.*, but peridot's require is "symfony/console": "^2|^3"</p>
  
  <p>I may be misunderstanding something, but doesn't ^2|^3 mean 2.* or 3.* will satisfy the requirements?</p>
  
  <p>My composer.json</p>
