Capistrano 部署命名空间

Question

所有 capistrano 文档似乎都表明有一个默认命名空间“部署”，其中包含一些标准任务，例如安装、更新代码、重新启动等。但是当我执行 cap -T 时，它只显示我定义的任务，而不显示部署任务。我还需要做其他事情来启用部署任务吗？我使用的是 capistrano 版本 2.9.0

项目根目录中是否有名为 Capfile 的文件？
我的如下

load 'deploy' if respond_to?(:namespace) # cap2 differentiator
Dir['vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }
load 'config/deploy'
