您好！我会尽量说得非常具体。很抱歉，在尝试部署应用程序时遇到了很多麻烦。我对rails完全陌生，所以我遵循了《敏捷Web开发与rails第4版》，我被困在了使用capistrano部署的部分。我已经尝试了书中的确切代码，但没有成功，并从这个论坛和其他论坛获得了一些建议，这些建议被证明是有帮助的，但我仍然无法正确部署我的部署。rb是这样的：
require 'bundler/capistrano'
set :user, 'user_created_for_this_example'
set :domain, 'IPADDRESS'
set :application, 'depot'
# file paths
set :repository, "#{user}@#{domain}:depot.git"
set :deploy_to, "/home/#{user}/#{domain}"
# set :scm, :git # You can set :scm explicitly or Capistrano will make an intelligent guess
based on known version control directory names
# Or: `accurev`, `bzr`, `cvs`, `darcs`, `git`, `mercurial`, `perforce`, `subversion` or `none`
#roles server
role :web, domain
role :app, domain
role :db, domain, :primary => true
#deploy config
set :deploy_to, "/home/#{user}/#{domain}"
set :deploy_via, :copy
set :scm, 'git'
set :branch, 'master'
set :scm_verbose, true
set :use_sudo, false
# if you want to clean up old releases on each deploy uncomment this:
# after "deploy:restart", "deploy:cleanup"
# if you're still using the script/reaper helper you will need
# these http://github.com/rails/irs_process_scripts
# 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
end
after "deploy:update_code", :bundle_install
desc "install the necesary prerequisites"
task :bundle_install, :roles => :app do
run "cd #{release_path} && bundle install"
end
当我运行cap-deploy:setup和cap-deploe:check时，一切似乎都很好：

但当cap-deploy:migrations、cap-deploy或cap-deploe:cold命令出现时，下一个弹出命令：

如果这是一个伪问题，一个简单的解决方案或已经发布的问题，我很抱歉，但我不知道还能尝试什么，再说一次，我只是从这些东西开始，我真的很失落。我在同一台机器上运行，所有的xx.xx.xx.xx代表我的ip地址。任何建议都将不胜感激。我试着尽可能具体，但如果有什么遗漏，我会把它发布出来。事先感谢你的时间和帮助。
您的问题是sftp的源位置和目的地位置相同：
** sftp upload /tmp/20121113173743.tar.gz -> /tmp/20121113173743.tar.gz
为了解决这个问题，您可以在config/deploy.rb文件中指定参数copy_dir，如下所示：
set :copy_dir, "/tmp/sftp"
则无需手动创建该文件夹。
尝试将此行添加到deploy.rb配置文件中：
default_run_options[:pty] = true
我们从更改了Capfile
set :deploy_via, :copy
至
set :deploy_via, :remote_cache
这对我们有效。我们没有添加下面的
default_run_options[:pty] = true
