I am a bit confused on how to install Rails 2 as a gem. When I run  
‘sudo gem install rails --source [http://gems.rubyonrails.org](http://gems.rubyonrails.org)’ it pulls  
down version 1.2.5.7919’. Is this the same as Rails2? I don’t think  
so … anyway, it seems that the only way I could get Rails 2 down was  
to check out the trunk (or the 2-0-0\_PR tag) from svn.

Hmmm … I am not sure what version to specify … the following does  
not work …

> sudo gem install rails --version ‘\> 1.2.5.7919’ --source [http://gems.rubyonrails.org](http://gems.rubyonrails.org)  
> ERROR: While executing gem … (Gem::GemNotFoundException)

I cannot seem to find any version (I tried specifying 2.0.0, ‘\>= 2’,  
etc.) that works.

Well Rails 2.0 doesn’t exist yet, it’s getting close but it’s not yet  
here.

AFAIK, the 1.2.5 gem is a packaged version of some recent snapshot of  
trunk.

And I’m reasonably sure that you can determine the difference between  
the 1.2.5 gem and the current state of edge rails with

$ svn diff [http://svn.rubyonrails.org/rails/trunk](http://svn.rubyonrails.org/rails/trunk)  
[http://svn.rubyonrails.org/rails/tags/rel\_1-2-5](http://svn.rubyonrails.org/rails/tags/rel_1-2-5)
