Ruby Version Confusion

Need a bit of help with installing Ruby and RoR

I installed everything initially last weekend (15/09/2012) including Ruby, RoR and RubyMine. I've just opened a Command Prompt on my win 7 64bit box and ran:

$ rails --version

which to my surprise returned 2.3.14 as I was expecting to see 3.2.8

I then ran:

$ gem install rails

Which output:

Successfully installed rails-3.2.8
1 gem installed
Installing ri documentation for rails-3.2.8...
Installing RDoc documentation for rails-3.2.8...

Then running rails --version again still outputs 2.3.14

I'm a bit confused why a new install (following the instructions here http://rubyonrails.org/download) seems to have installed a very old version.

How do I get the latest version installed?

Thanks,

I've gotten a bit further now. I ran:

F:\>gem cleanup rails
Cleaning up installed gems... Attempting to uninstall rails-2.3.14

You have requested to uninstall the gem:
    rails-2.3.14
restful_authentication-1.1.6 depends on [rails (~> 2.3.4)]
If you remove this gems, one or more dependencies will not be met.
Continue with Uninstall? [Yn]  y
Executables and scripts will remain installed.
Successfully uninstalled rails-2.3.14
Clean Up Complete

F:\>gem uninstall restful_authentication
Successfully uninstalled restful_authentication-1.1.6

F:\>gem install rails
Successfully installed rails-3.2.8
1 gem installed
Installing ri documentation for rails-3.2.8...
Installing RDoc documentation for rails-3.2.8...

F:\>rails -v
C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems.rb:317:in `bin_path': can't find ge
m rails ([">= 0"]) with executable rails (Gem::GemNotFoundException)
        from C:/Ruby193/bin/rails:23:in `<main>'

So now it's telling me that it's installed rails successfully but now errors when I query it's version.

Sounds like you have both versions installed. Run "gem uninstall rails" and it will list the versions and ask which one you want to remove. Then chose the old one to remove.
