Here is the gem list that I am using with ruby 1.9
actionmailer (2.3.4)
actionpack (2.3.4)
activerecord (2.3.4)
activeresource (2.3.4)
activesupport (2.3.4)
bigdecimal (1.1.0)
bundler-unload (1.0.2)
executable-hooks (1.3.2)
gem-wrappers (1.2.7)
io-console (0.3)
json (1.5.5)
minitest (2.5.1)
rack (1.0.1)
rails (2.3.4)
rake (0.9.2.2)
rdoc (3.9.5)
rubygems-bundler (1.4.4)
rubygems-update (1.8.25)
rvm (1.11.3.9)
sqlite3 (1.3.12)
sqlite3-ruby (1.3.3)
Note: I also downgraded my RubyGems to 1.8.25 as newer was not working with db:create rake command
In ruby 1.8 "abc"[0]
returns ASCII code of the first character (integer number 97) but in ruby 1.9 it returns string with the first character (string "a")
Integer number has method ^ but String doesn't.
You can try the following to fix this:
class String
def ^(value)
self.ord ^ value
end
end
This is probably not the best solution (maybe better to patch some method in rails).
Downgrading the Rails from 2.3.4 to 2.3.18 and rubyGems to 1.8.25 will fix the problem. Apparently Ruby 1.9.3 don't go well with 2.3.4
