In my command line I type script/server and I get the following error  
below:

/usr/local/lib/ruby/site\_ruby/1.8/rubygems.rb:826:in  
`report_activate_error': RubyGem version error: rack(0.9.1 not ~> 1.0.1) (Gem::LoadError) from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:260:in`activate’

from script/server:3

I see the rubygem version error, I get version 1.3.4 when I type gem -v  
at the command.

Kindest Regards

Yes, but it’s the rack version it is complaining about, not rails.

gem install rack -v=1.0.1

Cheers,
