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 ]

Answer 2

Try to use:

rvm --default use 1.9.2

Answer 3

PATH is probably wrong - check printenv PATH

Answer 4

I would go for bad gem/rails install:

gem empty
gem update --system
gem install bundler --no-ri --no-rdoc
gem install rails --no-ri --no-rdoc

Answer 5

Are you using Passenger or Pow to run your Rails apps? If so you'll need to set the server to use rvm 1.9.2

See section 2.3 here, for example: http://pow.cx/manual.html#section_2

Or for passenger: http://blog.phusion.nl/2010/09/21/phusion-passenger-running-multiple-ruby-versions/

Answer 6

Make sure you didn't use sudo with RVM. I ran into an issue like this where I had 2 different locations for Ruby and my gems.
