Forum: Ruby on Rails Help going from Rails 3.2.8 to 3.2.1

Hey everyone. I have rails 3.2.8 installed but I need 3.2.1 installed
either paralell with 3.2.8 or permently replacing it. I received work 
with
an existing 3.2.1 site, and the owner does not want to upgrade to 3.2.8.

I downloaded release 3.2.1 from GitHub however I can not figure out how 
to
install it. I tried running the *install.rb* script, but it fails
complaining that it cannot find the .gem files for multiple things
(activesupport, activemodel, ... etc).
So I tried running *gem install rails --version 3.2.1* and this says it
installed rails and I get this output:

----------------------------------------------------------
Successfully installed rails-3.2.1
1 gem installed
Installing ri documentation for rails-3.2.1...
Installing RDoc documentation for rails-3.2.1...
----------------------------------------------------------

but I cannot find out where it was installed to.

---------------------------------------------------------
$ /usr/bin/rails -v
Rails 2.3.14
$ /usr/local/bin/rails -v
Rails 3.2.8
$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]

You don't need to install rails 3.2.1 - just run bundle install from the
root of this app and bundler will take care of that for you. You'll
probably need to prefix rails commands with bundle exec (eg `bundle exec
rails console` instead of `rails console`)

Hey Fred,

I've ran bundle install, but when I want to start the server I get the
following error:

Error is the same for both 'rails server' and 'bundle exec rails server'

What else could I try?

Thanks

Add the ruby racer gem to your gem file otherwise install node js

Ian,

adding the ruby racer gem to the gem file worked.


Thank you both for your help, I appreciate it.
