To get the latest version, simply type: $ sudo gem install rails You can then rerun your "rails" command. More WTF: wbednarski@mbp13:~$ which rails /usr/bin/rails How is it possible that command rails exist but Rails is not installed and how to fix it? EDIT: wbednarski@mbp13:~$ sudo gem install rails Password: Successfully installed rails-3.1.3 1 gem installed Installing ri documentation for rails-3.1.3...
