当我执行cap deploy部署我的 rails 应用程序时，会显示以下输出：

... more stuff...

这样做的问题是 capistrano 在获取新代码后使用错误的目录来执行命令（deploy:update_code）。git clone 命令将检索到的文件存储到/var/www/releases/20130629231751目录中，但以下所有命令都使用旧版本 ( /var/www/releases/20130629230631)。结果是资产等被预编译为错误的版本。

我的config/deploy.rb样子是这样的：

set :application, "example"
set :repository,  "git@some-random-git-server.org:example.com.git"
set :deploy_to, "/var/www"

set :scm, :git
set :git_shallow_clone, 1

role :web, "example.org"
role :app, "example.org"
role :db,  "example.org", :primary => true

set :user, "some-user"
set :use_sudo, false

ruby_version = 'ruby-1.9.3-p392'
set :default_environment, {
  'PATH'         => "/usr/local/rvm/gems/#{ruby_version}/bin/:$PATH",
  'RUBY_VERSION' => "#{ruby_version}",
  'GEM_HOME'     => "/usr/local/rvm/gems/#{ruby_version}",
  'GEM_PATH'     => "/usr/local/rvm/gems/#{ruby_version}@global",
  'BUNDLE_PATH'  => "/usr/local/rvm/gems/#{ruby_version}",
  'TERM' => 'xterm'
}

如何解决此问题，以便 git clone 之后的命令在正确的目录上运行？
