Question

I am trying to install a gem like this:

C:\InstantRails\rails_apps\foodmarksthespot>ruby script/plugin install git://github.com/lazyatom/engines.git 

Which returns this message:

Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update --system` and try again. 

But when I try to update using:

gem update --system 

it says:

Updating RubyGems Nothing to update 

This is on windows. How can I force it to upgrade the system to a specific version?

From there:

 NOTE: RubyGems 1.1 and 1.2 have problems upgrading when there is no rubygems-update installed. You will need to follow the second set of update instructions if you see 'Nothing to update'.  If you have an older version of RubyGems installed, then you can still do it in two steps:  $ gem install rubygems-update (again, might need to be admin/root) $ update_rubygems (... here too)
