Forum: Rails deployment DB:Migrate - Rails requires RubyGems >= 1.3.2. Please install RubyGems and try again

Hello,

I've been trying to deploy a Ruby on Rails application and everything
works fine until it tries to run the DB migration scripts, at which
point it fails:

*** [err :: test-app1] Rails requires RubyGems >= 1.3.2. Please install
RubyGems and try again: http://rubygems.rubyforge.org
*** [err :: test-app1]
 ** [out :: test-app1] (in
/filestore/rails/test/releases/20101117194037)
    command finished
failed: "sh -c 'cd /var/rails/test/releases/20101117194037 && rake
RAILS_ENV=production db:util:migrate'" on test-app1

If I attempt to run the rake command manually to run the DB scripts, I
see the same error:
[root@test-app1 current]# rake RAILS_ENV=production db:util:migrate
(in /filestore/rails/test/releases/20101118220117)
Rails requires RubyGems >= 1.3.2. Please install RubyGems and try again:
http://rubygems.rubyforge.org

Here's some more info:

I've done many different things to no avail.  I removed RubyGems and
reinstalled it (1.3.1, 1.3.2), I upgraded my version of Ruby to
Enterprise 1.8.7.

Could someone please help me out?

Thank you,
Franck
