Capistrano 部署命名空间答案

【问题标题】：Capistrano deploy namespaceCapistrano 部署命名空间
【发布时间】：2011-12-13 10:12:38
【问题描述】：

所有 capistrano 文档似乎都建议有一个默认命名空间“部署”，其中包含一些标准任务，如 setup、update_code、restart 等。但是当我执行 cap -T 时，它只显示我定义的任务而不是部署任务。我是否需要做任何其他事情来启用部署任务。我正在使用 capistrano 版本 2.9.0

【解决方案2】：

您在项目根目录中有一个名为Capfile 的文件吗？我的跟随

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

【讨论】：

我没有使用 capify 生成 Capfile，因此它没有您提到的行。添加这些行后，它就可以工作了。
