script/generate not working ! while rails do

rubyonrails-talk
#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

RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.5
  - RUBY VERSION: 1.8.6 (2008-03-03 patchlevel 114)
[universal-darwin9.0]

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

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'.
