我正在尝试将我的“开发”分支部署到我的开发服务器，但是当我运行时cap development deploy，我收到以下错误：
executing "ln -nfs /var/www/xyz.co.uk/shared/web/media /var/www/xyz.co.uk/releases/20130311143220/web/media"
servers: ["x.xx.xx.xxx"]
[x.xx.xx.xxx] executing command
*** [err :: x.xx.xx.xxx] ln:
*** [err :: x.xx.xx.xxx] failed to create symbolic link `/var/www/xyz.co.uk/releases/20130311143220/web/media'
*** [err :: x.xx.xx.xxx] : No such file or directory
*** [err :: x.xx.xx.xxx]
command finished in 44ms
*** [deploy:update_code] rolling back
当我查看服务器/var/www/xyz.co.uk/shared/web/media已创建并/var/www/xyz.co.uk/releases/20130311143220已创建时，但一旦符号链接失败，则20130311143220在回滚时将其删除。有任何想法吗？我以 root 身份 ssh'ing。
Capifony 配置
部署.rb
set :stage_dir, 'app/config/deploy' # needed for Symfony2 only
set :stages, %w(production staging development)
set :application, "xyz.co.uk"
set :user, "root" # The server's user for deploys
set :repository, "git@github.com:xyz/#{application}.git"
set :scm, :git
set :keep_releases, 3
set :use_sudo, false
set :shared_files, ["app/config/parameters.yml"]
set :shared_children, [app_path + "/logs", web_path + "/media", "vendor"]
set :use_composer, true
set :update_vendors, true
set :dump_assetic_assets, true
require 'capistrano/ext/multistage'
logger.level = Logger::MAX_LEVEL
发展.rb
server 'x.xx.xx.xxx', :app, :web, :primary => true
ssh_options[:port] = xxxx
ssh_options[:forward_agent] = true
set :deploy_to, "/var/www/xyz.co.uk/"
set :symfony_env_prod, "test"
更新
实际的错误信息是：
failed: "sh -c 'ln -nfs /var/www/xyz.co.uk/shared/web/media /var/www/xz.co.uk/releases/20130312135615/web/media'" on x.xx.xx.xxx
另外，这是我的 .gitignore 文件：
/web/bundles/
/app/bootstrap*
/app/cache/*
/app/logs/*
/vendor/
/app/config/parameters.yml
composer.phar
/.idea/
/web/media/*
从我的 git 存储库中提取的用户名和密码在我的开发服务器上与在我部署的本地计算机上不同，这会有所不同吗？
