As previously mentioned  the bundler version may be too high for your version of rails   I ran into the same problem using Rails 3 0 1 which requires Bundler v1 0 0 - v1 0 22  Check your bundler version using  gem list bundler  If your bundler version is not within the appropriate range  I found this solution to work  rvm  global do gem uninstall bundler  Note  rvm is required for this solution    another case for why you should be using rvm in the first place

There are several other version managers to consider  see for a few examples and one that s not listed there that I ll be giving a try soon is ch-ruby  I tried rbenv but had too many problems with it  RVM is my mainstay  though it sometimes has the odd problem  hence my wish to try ch-ruby when I get a chance   I wouldn t touch the system Ruby  as other things may rely on it   I should add I ve also compiled my own Ruby several times  and using the Hivelogic article  as Dave Everitt has suggested  is a good idea if you take that route

With brew this is a one-liner    assuming that you have tapped homebrew versions  which can be done by running brew tap homebrew versions   brew install ruby193   Worked out of the box for me on OS X 10 8 4  Or if you want 2 0  you just brew install ruby  More generally  brew search ruby shows you the different repos available  and if you want to get really specific you can use brew versions ruby and checkout a specific version instead

I ll make a strong suggestion for rvm    It s a great way to manage multiple Rubies and gems sets without colliding with the system version     I ll add that now  4 2 2013   I use rbenv a lot  because my needs are simple  RVM is great  but it s got a lot of capability I never need  so I have it on some machines and rbenv on my desktop and laptop  It s worth checking out both and seeing which works best for your needs

I ll disagree with The Tin Man here  I regard rbenv as preferable to RVM  rbenv doesn t interfere drastically with your shell the way RVM does  and it lets you add separate Ruby installations in ordinary folders that you can examine directly  It allows you to compile Ruby yourself  Good outline of the differences here  https   github com sstephenson rbenv wiki Why-rbenv 3F  I provide instructions for compiling Ruby 1 9 for rbenv here  Further  more detailed information here  I have used this technique with easy success on Snow Leopard  Lion  and Mountain Lion

Dan Benjamin s Hivelogic article Installing Ruby  RubyGems  and Rails on Snow Leopard is the recommended place to go although the article is for 1 8  so here s a Ruby 1 9-specific install on Snow Leopard  Watch out for the 64-bit thing    either go all 64-bit  fat   as is - for example - Apache on OS X  which can cause problems with 32-bit libraries  or check any gems you re likely to use to make sure they re okay for 64-bit

As The Tin Man suggests  above  RVM  Ruby Version Manager  is the Standard for upgrading your Ruby installation on OSX  https   rvm io   To get started  open a Terminal Window and issue the following command    curl -L https   get rvm io   bash -s stable --ruby     you will need to trust the RVM Dev Team that the command is not malicious - if you re a paranoid penguin like me  you can always go read the source  https   github com wayneeseguin rvm   When it s complete you need to restart the terminal to get the rvm command working   rvm list known     shows you the latest available versions of Ruby    rvm install ruby-2 3 1   For a specific version  followed by  rvm use ruby-2 3 1   or if you just want the latest  current  version   rvm install current  amp  amp  rvm use current     installs the current stable release - at time of writing ruby-2 3 1 - please update this wiki when new versions released    Note on Compiling Ruby  In my case I also had to install Homebrew http   mxcl github com homebrew  to get the gems I needed  RSpec  which in turn forces you to install Xcode  if you haven t already  https   itunes apple com us app xcode id497799835 AND OR install the GCC package from  https   github com kennethreitz osx-gcc-installer to avoid errors running  make    Edit  As of Mavericks you can choose to install only the Xcode command line tools instead of the whole Xcode package  which comes with gcc and lots of other things you might need for building packages  It can be installed by running xcode-select --install and following the on-screen prompt    Examples  https   rvm io workflow examples  Screencast  http   screencasts org episodes how-to-use-rvm   Note on erros  if you get the error  RVM is not a function  while trying this command   visit  How do I change my Ruby version using RVM  for the solution

I know it s an older post  but i wanna add some extra informations about that  Firstly  i think that rvm does great BUT it wasn t updating ruby from my system  MAC OS Yosemite    What rvmwas doing   installing to another location and setting up the path there to my environment variable     And i was kinda bored  because i had two ruby now on my system    So to fix that  i uninstalled the rvm  then used the Homebrew package manager available here and installed ruby throw terminal command by doing brew install ruby   And then  everything was working perfectly   The ruby from my system was updated   Hope it will help for the next adventurers
