Installing Gems Error

What do I have to do to get permission to install gems in ANY directory ? This is the message I get : Kims-MBP:appliq Development$ gem install bcrypt ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory. What does is it mean and what do I have to do ?
