(Unable to start rails application) ruby scipt/server error

Rails
1

  1. I installed the ruby-1.9.2-p0 and rubygems-1.3.7 in the
    (/usr/local/src directory )

  2. Then i installed rails from terminal by typing follwoing

        sudo gem install rails --include-dependencies

  3. Then i made a rails applcation from terminal as

                     rails new demo
                      then
                cd demo
               ruby script/server

                Here i got the error

     <internal:lib/rubygems/custom_require>:29:in `require': no

such
file to load – script/…/config/boot (LoadError)
from internal:lib/rubygems/custom_require:29:in require' from script/server:2:in’

4)The details of script/serve file are as under

#!/usr/bin/env ruby
require File.dirname(FILE) + ‘/…/config/boot’
require ‘commands/server’

         Any suggesstion ??

thanks in advance

So you have rails3.0 installed?
Then you need to use “rails server” or “rails s” to start your
application.
