Cannot load such file -- script/../config/boot (LoadError)

Hello Friends,

I want to use multiple Rails versions on my system for different
applications. For this I have created Gemfile and place that file in
application folder. Then I have use bundle install command in
application directory. Its run without giving any error. But when I
run bundle exec script/server, it gives error (LoadError).

Gemfile includes :

source 'https://rubygems.org'

gem 'rails', '~> 2.3.8'

Then I run, $ bundle install in terminal. After that start the application using

$ bundle exec script/server

It gives following error:

$ bundle exec script/server
script/server:2:in `require': cannot load such file --
script/../config/boot (LoadError)
  from script/server:2:in `<main>'

Please help me to solve this problem.

from the error message, there’s no config/boot.rb file
