Capistrano v3 не смог найти Bundler

У меня возникла проблема с развертыванием моего приложения с Capistrano v3. Когда я запускаю '$ cap production deploy', я вижу ошибку...

 INFO [825ad68d] Running /usr/bin/env bundle --gemfile /home/username/www/myapp/releases/20131026181031/Gemfile --path /home/username/www/myapp/shared/bundle --deployment --quiet --binstubs /home/username/www/myapp/shared/bin --without development test on myhostname.com

DEBUG [825ad68d]    /usr/bin/env:

Но когда я запускаю последнюю команду...

cd /home/username/www/myapp/releases/20131026181031 && ( RAILS_ENV=production /usr/bin/env bundle --gemfile /home/username/www/myapp/releases/20131026181031/Gemfile --path /home/username/www/myapp/shared/bundle --deployment --quiet --binstubs /home/username/www/myapp/shared/bin --without development test )

... через ssh на моем сервере Я не вижу никаких ошибок.

Вот моя серверная среда:

• Ubuntu 13.04
• rvm 1.23.5
• rubygems 1.8.25
• Bundler 1.3.5
• ruby ​​1.9.3p448
• capistrano (3.0.0)
• capistrano-bundler (1.0.0)
• capistrano-rails (1.0.0)

Вот фрагмент моего Gemfile, который включает в себя capistrano gems

...
group :development do
  ...
  # Deploy with Capistrano
  gem 'capistrano', '~> 3.0.0'
  gem 'capistrano-rails'
  gem 'capistrano-bundler'
end
...

См. ниже конфигурацию capistrano:

    end
  end

    end
  end

Пожалуйста, помогите мне.

решаемые

Я решил проблему, выполнив следующие шаги:

Добавьте capistrano-rvm в Gemfile и сделайте

...
group :development do
  ...
  gem 'capistrano', '~> 3.0.0'
  gem 'capistrano-rails'
  gem 'capistrano-bundler'
  gem 'capistrano-rvm'
end
...

Добавьте эту строку в Capfile

require 'capistrano/rvm'

Добавьте эти строки в файл deploy.rb.

set :rvm_ruby_version, '1.9.3-p448'
set :default_env, { rvm_bin_path: '~/.rvm/bin' }
SSHKit.config.command_map[:rake] = "#{fetch(:default_env)[:rvm_bin_path]}/rvm ruby-#{fetch(:rvm_ruby_version)} do bundle exec rake"

Ответы

set :rvm_type, :system
set :rvm_ruby_version, 'ruby-<version>@<gemset>'
