                       rails new blog

        and the content of the file  "blog/config/boot.rb" are

           require ''rubygems''

# Set up gems listed in the Gemfile.
gemfile = File.expand_path(''../../Gemfile'', __FILE__)
begin

  require ''bundler''
  Bundler.setup
rescue Bundler::GemNotFound => e
  STDERR.puts e.message
  STDERR.puts "Try running `bundle install`."
  exit!
end if File.exist?(gemfile)


                           Now cd blog
                                  rails server             is working well

following error



Usage:
  rails new APP_PATH [options]

Options:

Rails options:

  -h, [--help]     # Show this help message and quit

Description:
    The ''rails new'' command creates a new Rails application
with a default
    directory structure and configuration at the path you specify.

Example:
    rails new ~/Code/Ruby/weblog

    This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
    See the README in the newly created application to get going.


                                     why this is happening even both are the
rails application .Please help me to run the server for openstreetview


Thanks for co-operation.

Hi Amritpal,
    OpenStreetView is a Rails version 2.3.4 application. There are large
differences between Rails2 and Rails3 which is causing your problem. To
solve your problem do the following:

       gem uninstall rails

       gem install rails -v 2.3.4

       cd OpenStreetView

       ruby script/server

Let me know if you need any further help.

Regards,

Luke
