Hi All, I’m trying to install RubyonRails on HP-UX 11.23[ia64-hpux11.23] machine. I was succesful in building Ruby1.8.7p160 and RubyGems1.3.2. #./ruby -v ruby 1.8.7 (2009-04-08 patchlevel 160) [ia64-hpux11.23] #./gem -v 1.3.2 Also my basic Ruby programs are working fine. On Installing RubyRails I got installation successful message: #gem install rails Successfully installed rake-0.8.7 Successfully installed activesupport-2.3.2 Successfully installed activerecord-2.3.2 Successfully installed actionpack-2.3.2 Successfully installed actionmailer-2.3.2 Successfully installed activeresource-2.3.2 Successfully installed rails-2.3.2 7 gems installed Installing ri documentation for rake-0.8.7… Installing ri documentation for activesupport-2.3.2… Installing ri documentation for activerecord-2.3.2… Installing ri documentation for actionpack-2.3.2… Installing ri documentation for actionmailer-2.3.2… Installing ri documentation for activeresource-2.3.2… Installing RDoc documentation for rake-0.8.7… Installing RDoc documentation for activesupport-2.3.2… Installing RDoc documentation for activerecord-2.3.2… Installing RDoc documentation for actionpack-2.3.2… Installing RDoc documentation for actionmailer-2.3.2… Installing RDoc documentation for activeresource-2.3.2… However when i run ./rails i get following error: # ./rails undefined method `camelize’ for “app”:String Please help me in resolving this error. I saw similar error posts but could not conclude what the problem actually is. Thanks in advance for the help 🙂
