Changing rvm_ruby_version doesn't change the ruby version

Question

In my deploy.rb I have set :rvm_ruby_version, '1.9.3'

In ../shared/bundle/ruby/ I see 1.9.1

Why is this not 1.9.3?

Update

I added ruby 1.9.3 to my gemfile. I am seeing commands like this:

/home/rails/.rvm/rubies/ruby-1.9.3-p448/bin/ruby /home/rails/rails-capistrano/shared/bundle/ruby/1.9.1/bin/rake assets:precompile:all RAILS_ENV=staging RAILS_GROUPS=assets

Why go into bundle/ruby/1.9.1?

Answer 1

1.9.1 is a ruby compatibility version, this means that all 1.9.x rubies are supposed to be binary compatible
