title: Heroku rake db:migrate doesn't work
body: <p>Ruby 1.9.2 Rails 3.1</p>
  
  <p>After the day of fighting with heroku issues I was able to finally have the command 'git push heroku master to work properly'. </p>
  
  <p>Gemfile has proper enties and pg gem is installed</p>
  
  <pre><code>group :production do
    gem 'pg'
  end
  group :development, :test do
    gem 'sqlite3'
  end
  </code></pre>
  
  <p>At this point application has been uploaded and start page can be viewed here <a href="http://growing-day-7939.heroku.com/" rel="nofollow">http://growing-day-7939.heroku.com/</a></p>
  
  <p>The next step should be migrating the database to the heroku with 'heroku rake db:migrate"
  and it always fails. </p>
  
  <pre><code>c:\RailsInstaller\work\rfclub&gt;heroku rake db:migrate
  No app specified.
  Run this command from an app folder or specify which app to use with --app &lt;app name&gt;
  </code></pre>
  
  <p>Other heroku commands fail with the same error as above - heroku ps, heroku logs, heroku config.</p>
  
  <p>I've tried deleting and recreating the app, even tried creating the new heroku account and repeating the steps, but nothing seems to help.
  Any ideas would be appreciated, I'm really stuck.</p>
