Rails - Sep 2008 - error message 'undefined method `require_gem' for main:Object (NoMethodError)'--how to resolve?

I''m getting the following when doing a db:migrate after installing RoR
2+:

Macintosh-4:ui Ken$ rake db:migrate
/usr/local/bin/rake:17: undefined method `require_gem'' for main:Object
(NoMethodError)

I have done a '' sudo gem update --system''. Any thoughts as to
what
might be causing this?

This is on OS X 10.5

Thanks,
Ken

Your app was written for an old version of rubygems. require_gem was
deprecated a while back (replaced with gem) and eventually removed.
If you''ve just updated your app to a new version of rails, then
running rake rails:update will update things like boot.rb which may
have been using require_gem

require_gem ''gemname''

is now to

require ''rubygems''
require ''gemname''

This is how you convert.

Heh, rake rails:update gives the same error. Sigh. Advice much  
appreciated, though.

Apparently I have an old lib of some sort hanging around that needs to  
be updated, but
I don''t know how to find out what it is, let alone do the update. I am
running rails 2.x.

Thanks,
Ken

Unfortunately, it''s not my code that''s causing the problem,
and I
don''t know what is out of date that I need
to update. This all started when I upgraded to RoR 2.x (with  
dependencies). I can''t do anything about the
code that''s in there, except try to figure out how to upgrade whatever
is using this call.

Thanks,
Ken

''rake'' itself is a gem.

Can you try

sudo gem update rake

?

Ah well you''ll just have to fix the files yourself. replace  
occurrences of require_gem with gem

The error was obvious from the error message, once I looked at it  
closely; I needed to ''gem install rake'' :-)

Thanks,
Ken
