当使用 capistrano 部署我的 Rails 应用程序时，安装所有内容并回滚并显示以下错误
failed: "rvm_path=/usr/local/rvm /usr/local/rvm/bin/rvm-shell 'ruby-2.0.0-p247' -c 'cd /var/www/vhosts/admin/releases/20131012184713 && bundle install --gemfile /var/www/vhosts/admin/releases/20131012184713/Gemfile --path /var/www/vhosts/admin/shared/bundle --deployment --quiet --without development test'" on admin.mydomain.com

这是我的 deploy.rb：
require "bundler/capistrano"
require "rvm/capistrano"
set :rvm_ruby_string, "ruby-2.0.0-p247"
set :rvm_type, :user
set :application, "admin"
set :repository, "git@bitbucket.org:username/myrepo.git"
set :user, "my-server-user-name"
set :branch, "master"
set :deploy_to, "/var/www/vhosts/admin"
set :deploy_via, :copy
set :use_sudo, false
set :rvm_install_with_sudo, true
default_run_options[:pty] = true
set :port, 2775
set :scm, :git
role :web, "admin.mydomain.com"
role :app, "admin.mydomain.com"
role :db, "admin.mydomain.com", :primary => true
role :db, "admin.mydomain.com"
after "deploy:update_code","deploy:config_symlink"
set :rvm_type, :system
# If you are using Passenger mod_rails uncomment this:
namespace :deploy do
task :start do ; end
task :stop do ; end
task :restart, :roles => :app, :except => { :no_release => true } do
#run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
end
task :config_symlink do
#run "cp #{release_path}/config/database.yml.example #{release_path}/config/database.yml"
end
end
before 'deploy', 'rvm:install_ruby'
before 'deploy', 'rvm:create_gemset'
我没有在此处显示任何特定错误。上述错误是我收到的唯一消息。
还有一点要说的是
在我的服务器中，我可以找到此路径
/usr/local/rvm但我找不到/usr/local/rvm/bin/rvm-shell。

我尝试gem install pg -v '0.17.0'并添加bundle config build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config了，但存在上述错误我该如何解决
