This is from a fesh install of rails-1.2.3 with dependencies from a fresh install of rubygems. I even tried uninstalling everything and installing each dependency manually from gems.

Same result on x86_32 and x86_64 version of Ubuntu 7.04 (feisty)

  • milestone changed from 1.x to 1.2.4.

You're missing some Ruby packages and it's preventing Active Support, which has write_inheritable_attribute, from loading.

Try 

require 'rubygems'
require 'activesupport'

in irb and see whether it raises a LoadError.

  • status changed from closed to reopened.
  • resolution deleted.

i reproduced the defect. the cause is i install activesupport using gem and the folder is activesupport-1.4.2 something. but i noticed in rails_generator.rb,

line2: $:.unshift(File.dirname(FILE) + "/../../activesupport/lib")

after i rename the autogenerated folder activesupport-1.4.2 to activesupport, everything is fine.

  • cc set to tarmo.

tailorcai, if you installed activesupport from a gem then it should be in "activesupport-1.4.2". The unshift line is just to make sure that if gems are not used (for example vendor/rails is used) then activesupport gets loaded from the proper directory.

This happened with a new install of rails 2.2.2:

I'm running:

With Ruby: ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-freebsd7]

Gems: 1.3.1

If I install rails 2.1.0, then "rails floog" works perfectly.
