title: heroku keys:add error
body: <p>I'm a beginner in Rails and I've followed ruby.railstutorials.org until I stuck with this section <a href="http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:1.4.1" rel="nofollow">http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:1.4.1</a></p>
  
  <p>after I installed heroku gem by <code>gem install heruku</code></p>
  
  <p>I typed <code>heroku keys:add</code> then I got these errors.</p>
