I had just installed Rails 2.1.0, or at least that’s the feedback I got  
when I typed “gem install rails”

However, when I look in my gem paths I see that rails-1.2.6 is the only  
directory there.

Am I missing something. Is Rails 2.1.0 stored somewhere else (gem  
environment gave me two paths, I checked them both).

Sorry if this is a stupid question, I’m still finding my way around.

Thanks!

If you installed any previous versions of rails…  
first remove completely then install latest version

if you want to remove gems  
in the command line type “sudo apt-get autoremove rubygems”

Hi Akins,

Path : C:\ruby\lib\ruby\gems\1.8\gems

C:\Documents and Settings\raveendran\>gem list | grep rails  
Brightbox rails deployment scripts for Capistrano  
rails (2.1.0, 1.2.3)  
(like the rails command does for Ruby on Rails, and the

C:\Documents and Settings\raveendran\>gem install rails # for latest  
version  
C:\Documents and Settings\raveendran\>gem install rails -v1.1.6 # for  
particular version

OK, forgive me for this.

I’m using jruby. And I assumed that calling ‘jruby -S gems’ was the  
same as just using ‘gems’

Stupid assumption.

Turns out the gems paths were different.

I was kinda hoping that I wouldn’t have to use the jruby list for  
everything, thinking that in some cases asking Gems questions and Rails  
questions on their dedicated forums will get me better responses.

Of course, that assumes I’m asking good questions, which in this case I  
didn’t.

What does `gem list` say?
