使用 Capistrano（RoR 应用程序）部署到 RVM 环境

Question

我一直在四处寻找问题的答案，但找不到可行的解决方案...所以这是我在 stackoverflow 上的第一篇文章！

不久前，我使用 RVM 设置了一个 apache 服务器，以便托管我客户的一个网站。到那时，我的开发环境也已经通过 rvm 安装了 ruby​​。同时，我改变了我的开发环境，现在开始在 Ubuntu 上使用 VM VirtualBox，并使用apt-get install ruby 直接从源代码安装 ruby​​。我使用 Capistrano 部署了我的所有项目。

现在我已经对该项目进行了一些工作，但是当我尝试将其部署到生产服务器时，我收到了以下错误：

2013-07-08 08:12:50 executing `bundle:install'
* executing "cd /var/www/project/releases/20130708061242 && bundle install --gemfile /var/www/project/releases/20130708061242/Gemfile --path /var/www/project/shared/bundle --deployment --quiet --without development test"

我也有自己的测试服务器，在这个服务器上部署时我没有问题（它有 rbenv）。

服务器端的东西是我最不了解的领域 :) 如果我可以提供您可能需要的任何其他信息，请告诉我。

谢谢！

这是我的 deploy.rb

require "bundler/capistrano"
require "rvm/capistrano"

server "xxx.xx.xxx.xxx", :app, :web, :db, :primary => true

set :rvm_ruby_string, ENV['GEM_HOME'].gsub(/.*\//,"")
set :rvm_install_ruby_params, '--1.9'      # for jruby/rbx default to 1.9 mode
set :rvm_install_pkgs, %w[libyaml openssl] # package list from https://rvm.io/packages
set :rvm_install_ruby_params, '--with-opt-dir=/usr/local/rvm/usr' # package support

before 'deploy:setup', 'rvm:install_rvm'   # install RVM
before 'deploy:setup', 'rvm:install_pkgs'  # install RVM packages before Ruby
before 'deploy:setup', 'rvm:install_ruby'  # install Ruby and create gemset, or:
before 'deploy:setup', 'rvm:create_gemset' # only create gemset
before 'deploy:setup', 'rvm:import_gemset' # import gemset from file

#General settings
set :ssh_options, { :forward_agent => true }
set :application, "project"
set :repository,  "git@repo.com:project.git"
set :deploy_to, "/var/www/#{application}"
set :deploy_via, :remote_cache

set :scm, :git
set :scm_user, "deploy"
set :user, :deploy
set :use_sudo, false
set :keep_releases, 5

after "deploy:update_code", "deploy:migrate"
load "deploy/assets"

将deploy.rb 的顶部更改为：

require "bundler/capistrano"
require "rvm/capistrano"

server "xxx.xx.xxx.xxx", :app, :web, :db, :primary => true

set :rvm_ruby_string, :local

before 'deploy:setup', 'rvm:install_rvm'   # install RVM
before 'deploy:setup', 'rvm:install_ruby'  # install Ruby and create gemset

#General settings
