I bought AWDWR 2nd edition by Dave T… I downgraded to rails 1.2.1
by:
sudo gem install --source http://gems.rubyforge.org rails -v 1.2.1
–include-dependencies
I inserted the following line in environment.rb
#RAILS_GEM_VERSION = ‘2.0.2’ unless defined? RAILS_GEM_VERSION
RAILS_GEM_VERSION = ‘1.2.1’
I followed each and every line of the book until p.67/p.68. I started
the server. I got the following errors.
=> Booting Mongrel (use ‘script/server webrick’ to force WEBrick)
=> Rails application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at 0.0.0.0:3000
** Starting Rails with development environment…

What is wrong with my copying work?
Thanks for your help.
