Cannot Install Rails Application with Capistrano and RVM

I have a Rails application that I have deployed with Capistrano. I installed RVM on the server since I wanted to use a newer version of Ruby and added this to my deploy.rb file (according to the different instructions I found):

$:.unshift(File.expand_path('./lib', ENV['rvm_path'])) require 'rvm/capistrano' set :rvm_ruby_string, '1.9.2' set :rvm_type, :user

When I run cap deploy , this happens:

  [staging.example.com] executing command ** [out :: staging.example.com] /usr/local/lib/site_ruby/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem bundler (>= 0) ( ** [out :: staging.example.com] Gem::LoadError) ** [out :: staging.example.com] from /usr/local/lib/site_ruby/1.8/rubygems.rb:214:in `activate' ** [out :: staging.example.com] from /usr/local/lib/site_ruby/1.8/rubygems.rb:1082:in `gem' ** [out :: staging.example.com] from /usr/bin/bundle:18 command finished in 801ms *** [deploy:update_code] rolling back * executing "rm -rf /home/example/staging.example.com/releases/20110714180125; true" servers: ["staging.example.com"] [staging.example.com] executing command command finished in 895ms failed: "rvm_path=$HOME/.rvm/ /usr/local/bin/rvm-shell '1.9.2' -c 'bundle install --gemfile /home/example/staging.example.com/releases/20110714180125/Gemfile --path /home/example/staging.example.com/shared/bundle --deployment --quiet --without development production'" on staging.example.com

Why is capistrano using Ruby 1.8? My path is clearly confused.

Here's the rvm info output on staging.example.com:

In fact, recent docs on the rvm-capistrano documentation page indicate that it should be something like this:

 # RVM bootstrap: change to your Ruby and GemSet require 'rvm/capistrano' set :rvm_ruby_string, ENV['GEM_HOME'].gsub(/.*\//,"") set :rvm_type, :user

  failed: "rvm_path = $ HOME / .rvm / / usr / local / bin / rvm-shell '1.9.2' -c 'bundle install --gemfile /home/example/staging.example.com/releases/20110714180125/Gemfile --path /home/example/staging.example.com/shared/bundle --deployment --quiet --without development production '

Make sure you have the package installed and the right path when running bundle install on the server. If it is not installed, run gem install bundler to install.

If you have the package installed, do the following:

Change this line -> set :rvm_ruby_string, '1.9.2'

to this -> set :rvm_ruby_string, 'ruby-1.9.2-p180'

it works for me.

to find out your versions of rubys - rvm list
