我在使用 Capistrano v3 部署我的应用程序时遇到问题。当我运行“$ cap production deploy”时，我看到一个错误......
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

但是当我运行最后一个命令时......
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 )
...通过我服务器上的 ssh 我没有看到任何错误。
这是我的服务器环境：
- Ubuntu 13.04
- 转速 1.23.5
- 红宝石 1.8.25
- 捆绑器 1.3.5
- 红宝石 1.9.3p448
- capistrano (3.0.0)
- capistrano 捆绑器 (1.0.0)
- capistrano-rails (1.0.0)
这是我的 Gemfile 的一部分，其中包括 capistrano 的宝石
...
group :development do
...
# Deploy with Capistrano
gem 'capistrano', '~> 3.0.0'
gem 'capistrano-rails'
gem 'capistrano-bundler'
end
...
请看下面 capistrano 的配置：

require 'capistrano/deploy'

end

请帮我。
解决了
我通过以下步骤解决了我的问题：
将 capistrano-rvm 添加到Gemfile并执行
...
group :development do
...
gem 'capistrano', '~> 3.0.0'
gem 'capistrano-rails'
gem 'capistrano-bundler'
gem 'capistrano-rvm'
end
...
将此行添加到 Capfile
require 'capistrano/rvm'
将这些行添加到deploy.rb文件中。
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"
