hi there - attempting to sudo gem install rails --pre on a system  
running ruby enterprise-1.8.7-2010.02.

however, I’m getting an error: active model requires i18n

before you say anything, I already ran the dependent gems install, too:

gem install tzinfo builder memcache-client rack rack-test rack-mount  
erubis mail text-format thor bundler i18n

before that, however, I ran a gem update --system, which updated my  
rubygems to 1.3.7 from 1.3.6

to gem install i18n, it says I require rubygems 1.3.6

ugh

is there a way to rollback rubygems to the prior version?  
or is there another way to fix this rails 3 install issue I’m having  
with i18n?

much thanks!

Still receive error installing rails: active model requires i18n  
When I try to sudo gem install i18n, it errors out because it requires  
RubyGems 1.3.6 or higher. I have RubyGems 1.3.7 installed. WTF?

I got this to work by reinstalling RubyGems via source files in the  
original Ruby directory (which is probably the same thing as changing  
the PATH, huh?). Dunno, but it works now! Thanks!

I received this error too after installing Ruby Enterprise Edition  
(REE).  
RubyGems apparently knows which version or at least path of Ruby it was  
installed with and complains in the very unhelpful way you noted about  
the  
conflict. Try changing your PATH shell variable so MRI Ruby is before  
REE  
Ruby.

HTH,  
Jeffrey
