title: "You don't have write permissions for the /usr/bin directory." when installing Sass using the Gem command
body: <p>I'm on Mac and I'm trying to install Sass using the command in terminal, "sudo gem install sass".  I then enter my password, and everything works fine until this pops up,</p>
  
  <p>"ERROR:  While executing gem ... (Gem::FilePermissionError)
      You don't have write permissions for the /usr/bin directory."</p>
  
  <p>I do use sudo, but it still doesn't work, and it's one of those things that you can't give yourself read &amp; write permissions to.  Any ideas?</p>
  
  <p>Thanks,</p>
  
  <p>Wade</p>
