Deployment 在deploy.rb中创建符号链接的正确方法

部署应用程序时出现错误：

    [neon.locum.ru] executing command
*** [err :: neon.locum.ru] find: `/home/hosting_grandinvest/projects/demo/releases/20130116145843/public/images /home/hosting_grandinvest/projects/demo/releases/20130116145843/public/stylesheets /home/hosting_grandinvest/projects/demo/releases/20130116145843/public/javascripts': Нет такого файла или каталога
    command finished in 91ms
    triggering after callbacks for `deploy:update_code'

  * executing "ln -s /home/hosting_grandinvest/projects/demo/shared/public/images /home/hosting_grandinvest/projects/demo/releases/20130116145843/public/images"

正如您所看到的，这是因为它首先尝试查找/public/images目录。然后才为该目录创建一个符号链接。 请求我的deploy.rb

require 'bundler/capistrano'
after "deploy:update_code", :make_images_link
task :make_images_link, roles => :app do
  images_dir = "#{shared_path}/public/images"
  run "ln -s #{images_dir} #{release_path}/public/images"
end

部署结束

当我部署错误仍然存在，但图像出现

最后，我在我的存储库中加入了“public”images目录。
作为步骤2，我运行了一个在更新1中指定的回调

after "deploy:update_code", :make_images_link
task :make_images_link, roles => :app do
  images_dir = "#{shared_path}/public/images"
  realease_images = "#{release_path}/public/images"
  run "rm -rf #{realease_images}"
  run "ln -s #{images_dir} #{realease_images}"
end
