Script/generate not working ! while rails do

Rails
1

Hi
Strange thing happens when i run rails project it makes project but when
i run script/generate or script/server it writes

Missing the Rails 2.3.5 gem. Please gem install -v=2.3.5 rails, update
your RAILS_GEM_VERSION setting in config/environment.rb for the Rails
version you do have installed, or comment out RAILS_GEM_VERSION to use
the latest version installed.

so rails -v gives Rails 2.3.5

How to fix that kind of problem ? i use mac and my “gem environment” is

What does the environment.rb show as the rails version?

Specifies gem version of Rails to use when vendor/rails is not present

RAILS_GEM_VERSION = ‘2.3.5’ unless defined? RAILS_GEM_VERSION

This happened to me yesterday too.

Weird, did you install any gems before that? I had a couple gems
installed I
think that something broke up that =/

I can’t help much not being a mac man, but I believe that this can
happen if rails is installed twice in different places. Google for
‘missing the rails gem’ might help.

Exactly, i have 1.2.3 1.2.6 installed to
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8
and 2.3.5 version here
/Library/Ruby/Gems/1.8

don’t know what default is - i guess it’s /Library/Ruby/Gems/1.8

i removed files from that directory
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8
but it didn’t help.
So in file “server” (script/server) we have 2 lines of code

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

first line load boot file and in booot file we have that line that loads
gems

class GemBoot < Boot
def load_initializer
self.class.load_rubygems
load_rails_gem
require ‘initializer’
end

def load_rails_gem
  if version = self.class.gem_version
    gem 'rails', version
  else
    gem 'rails'
  end
rescue Gem::LoadError => load_error
  $stderr.puts %(Missing the Rails #{version} gem. Please `gem

install -v=#{version} rails`, update your RAILS_GEM_$
exit 1
end

i am not an expert in ruby so far but i guess this function returns
false
“load_rails_gem” and this expression returns false “gem ‘rails’” so it’s
a gem method but what it’s doing ?

Can you post the output of ‘gem list --local’? I’m guessing that
you’re missing one of the dependencies somehow.

Well, that was a wash. I don’t see anything missing on the list; as
others have noted, do you happen to have a second Ruby installed? Try
running ‘/usr/bin/env ruby’.
