title: How to install gemfile on osx?
body: <p>I am trying to install the following gem from the command line following the instructions:
  <a href="https://github.com/maxdemarzi/neography" rel="nofollow">https://github.com/maxdemarzi/neography</a></p>
  
  <p>Executing:
  gem 'neography'</p>
  
  <p>Results in "Unknown command neography".</p>
  
  <p>I have "bundle" gem installed from executing "gem install bundle".</p>
  
  <p>What step am I missing? Does this have to be done for each individual project? Or is this supposed to install to environment?</p>
