ruby-Capistrano deploy.rb文件中的任务问题

我从this tutorial中获取了我的deploy.rb文件中的以下内容,除touch命令外,其他所有内容均按预期工作.

有谁知道为什么这可能行不通？

set :application, "your-application-name"
set :repository, "[email protected]:you/your-project.git"
set :scm, :git
set :deploy_to, "/home/path/to/project/"
set :use_sudo, false

set :deploy_via, :remote_cache
set :copy_exclude, [".git", ".DS_Store", ".gitignore", ".gitmodules"]

server "example.org", :app

namespace :myproject do
    task :symlink, :roles => :app do
        run "ln -nfs #{shared_path}/uploads #{release_path}/application/wp-content/uploads"
        run "touch #{release_path}/env_production"
    end
end

after "deploy:create_symlink", ":after_deploy" 

上限部署的输出

解决方法:

在当前的Capistrano版本中,默认任务deploy：symlink已弃用,并已由deploy：create_symlink代替

要使其正常运行,请将最后一行更改为：

after "deploy:create_symlink", "myproject:symlink"

请参阅capistrano/recipes/deploy.rb line 294 and following.您应该已经在Capistrano输出中看到过时警告.为了使Capistrano输出更具可读性,我强烈建议capistrano_colors gem.
