title: How to install a gem globally without sudo using rbenv?
body: <p>I am using <code>rbenv</code> and I am trying to install <code>sass</code> without success.</p>
  
  <p>So, I installed <code>rbenv</code> via <a href="http://brew.sh" rel="noreferrer">Homebrew</a>, then Ruby 2.2 (<code>rbenv install 2.2</code>) and finally <code>gem install sass</code>, but I was unable to make <code>sass</code> available on my <code>$PATH</code>.</p>
  
  <p>Short on time, I <code>sudo gem install sass</code> using my system's (Yosemite) default Ruby 2. This put everything in <code>/Library/Ruby/Gems/2.0.0</code> and things do work, but not in the most desireable way.</p>
  
  <p>Ideally, using <code>rbenv</code> I should be able to install any Ruby version and have gems installed inside that version's directory and later symlinked to <code>/usrl/local/bin</code>.</p>
  
  <p>Any help as to what could have gone wrong would be very much appreciated.</p>
