Rails not using correct version of Ruby

Question

New information

This is what happens with rails console:

Loading development environment (Rails 3.1.1)
ruby-1.9.2-p290 :001 &         


        

Answer 1

You should set default ruby like:

rvm use 1.9.2 --default

This will override system installed ruby with rvm one.

Updated:

notme, thank you for remark

Leading double hyphen before default is significant to set default ruby.

Below listed detailed & self-explained example, enjoy:

$ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-linux]

$rvm list
rvm rubies

   ruby-1.9.2-p290 [ i386 ]

$rvm use 1.9.2 --default
Using /usr/local/rvm/gems/ruby-1.9.2-p290

$rvm list default

Default Ruby (for new shells)

   ruby-1.9.2-p290 [ i386 ]

$rvm use default
Using /usr/local/rvm/gems/ruby-1.9.2-p290

$ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]

$rvm list 

rvm rubies

=> ruby-1.9.2-p290 [ i386 ]
