cap deploy:cold 后出现此错误（我更改了用户名和 IP）：

我基本上遵循了 railscasts 剧集“部署到 vps”的说明。这是我的 deploy.rb 文件：
require "bundler/capistrano"
server "192.33.333.333", :web, :app, :db, primary: true
set :application, "captest"
set :user, "user"
set :deploy_to, "/home/#{user}/apps/#{application}"
set :deploy_via, :remote_cache
set :use_sudo, false
set :scm, "git"
set :repository, "git@github.com:user/#{application}.git"
set :branch, "master"
default_run_options[:pty] = true
ssh_options[:forward_agent] = true
after "deploy", "deploy:cleanup" # keep only the last 5 releases
namespace :deploy do
task :start do; end
task :stop do; end
task :restart, roles: :app, except: {no_release: true} do
run "touch #{deploy_to}/current/tmp/restart.txt"
end
task :setup_config, roles: :app do
sudo "ln -nfs #{current_path}/config/apache.conf /etc/apache2/sites-available/#{application}"
run "mkdir -p #{shared_path}/config"
put File.read("config/database.example.yml"), "#{shared_path}/config/database.yml"
puts "Now edit the config files in #{shared_path}."
end
after "deploy:setup", "deploy:setup_config"
end
我尝试直接从服务器进行捆绑安装，但不知道在哪里，因为我对应用程序结构感到困惑。还尝试了“需要 rvm/capistrano”，但也出现错误。
