Hi,
According to its release notes, Rails 2.3.2 should run fine on Ruby
1.9.1. Since I''ve read about substantial performance gains from 1.9, I
decided to upgrade.
I built and installed Ruby 1.9.1-p129 on my server (Ubuntu 9.04, amd64
CPU) without any problems. Similarly, I was able to install Rails
2.3.2 via "gem" without any problems.
Unfortunately, Rails itself fails to function. Running the "rails"
script fails with the following error:
<internal:gem_prelude>:234:in `push_gem_version_on_load_path'':
Could
not find RubyGem activesupport (>= 0) (Gem::LoadError)
And trying to require one of the component gems also fails, as
follows:
irb(main):001:0> require "activerecord"
LoadError: no such file to load -- i18n/backend/simple
from /opt/ruby-1.9.1-p129/lib/ruby/gems/1.9.1/gems/
activerecord-2.3.2/lib/active_record/i18n_interpolation_deprecation.rb:
5:in `require''
Installing the "i18n" gem merely causes further problems, as follows:
irb(main):001:0> require ''activerecord''
NoMethodError: undefined method `alias_method_chain'' for
I18n::Backend::Simple:Class
from /opt/ruby-1.9.1-p129/lib/ruby/gems/1.9.1/gems/
activerecord-2.3.2/lib/active_record/i18n_interpolation_deprecation.rb:
23:in `<class:Simple>''
What follows is a list of the installed gems on my system:
[zhaytee@orzhova] ~$ gem list
*** LOCAL GEMS ***
actionmailer (2.3.2)
actionpack (2.3.2)
activerecord (2.3.2)
activeresource (2.3.2)
activesupport (2.3.2)
fastthread (1.0.7)
i18n (0.1.0)
passenger (2.2.2)
pg (0.8.0)
rails (2.3.2)
rake (0.8.4)
Is Rails 2.3.2 simply not compatible with 1.9.1, despite what the
release notes say? Any help would be greatly appreciated.

I guess I was too cocky, because I get the error you describe after building ruby 1.9.1p129 from source and installing Rails 2.3.2 on my shiny new iMac running Leopard. Some gems are fine, e.g., irb(main):002:0> require ''haml'' => true but some of the Rails gems, or things that depend on them, conk out in the way you describe. I checked my GEM_PATH, and everything is where Ruby should be looking. Would love to hear suggestions.> Is Rails 2.3.2 simply not compatible with 1.9.1, despite what the > release notes say?

You''ll to need to poke around for forks people have hacked together to get those working. Steve -- Posted via http://www.ruby-forum.com/.
Steve, try freezing your rails gems before starting the server and let me know what happens. -- Posted via http://www.ruby-forum.com/.
Hi ZhayTee, It sounds like ruby 1.9.1 isn''t being used to run your app. Make sure all symlinks to the ruby interpret point to 1.9. Also, you will need to reinstall gem with ruby 1.9.1 and then re-download and install the rails gems with the new gem install for 1.9. Worked for us.
