Dear Friends,

I am having trouble with the rails version. I am looking at the book  
by Sam, Dave and David, where they said if I install InstantRails 2.0,  
it comes with Rails 2.2.2. But apparently when I actually downloaded  
it from ([http://rubyforge.org/frs/download.php/29867/InstantRails-2.0-](http://rubyforge.org/frs/download.php/29867/InstantRails-2.0-)  
win.zip), and then (unzipped it → ran instantrails.exe → opened Ruby  
Console window from the I icon etc),

I issued the command rails -v and it says Rails is version 2.0.2.

So I wanted to upgrade it to 2.2.2. To do that, I gave the  
instructions from the book

gem install rails --version 2.2.2,

but I get the error:

Updating metadata for 1 gems from [http://gems.rubyforge.org](http://gems.rubyforge.org)  
.  
complete  
ERROR: could not find rails locally or in a repository

What am I missing?

Environment: Windows XP SP3  
InstantRails 2.0

Have you tried running “gem update --system”? Just a guess…hope it  
helps.

I would suggest you try 'gem list -r' to see if there are any remote gems in the repository you are contacting.&nbsp; That should give you some&nbsp; information on what is there.&nbsp; I have personally upgraded InstantRails 2.0 from 2.0.2 to 2.2.? and&nbsp; I cannot recall any particular problems doing it.&nbsp; Updating gem as suggested may help.
