How do I change Rails environment on OpenShift?
<p>I'm trying to set up this application to run in Development mode but the default environment on Openshift seems to be Production or Deployment</p>

<p>I tried to change gems versions on the server and it throwed:</p>

<blockquote>
  <p>You are trying to install in deployment mode after changing
  your Gemfile. Run <code>bundle install</code> elsewhere and add the
  updated Gemfile.lock to version control.</p>
  
  <p>If this is a development machine, remove the Gemfile freeze 
  by running <code>bundle install --no-deployment</code>.</p>
</blockquote>

<p>But I didnt manage to find a way to change my environment. When I hit <code>rhc env list my_app</code> nothing happens</p>

<p>How do I change my environment on Openshift so everything I do is on Development mode?</p>
