：更新钩子后找不到任务

问题描述

下面是lib / capistrano / tasks / load_seeds.rake的内容。 如果我将'after：updating'行更改为'before：updating'，则该任务将在适当的时间执行。如果如图所示运行，它将生成“任务：未找到load_seeds”。请参阅任务列表下方的转储。

当然想知道问题出在哪里。谢谢！ Capistrano版本：3.14.1（Rake版本：12.3.3）

namespace :deploy do
  namespace :check do
    desc "Execute rake db:seed"
    after :updating,:load_seeds do
      on roles(:app),in: :sequence do
        puts "\n=== Seeding Database ===\n"
#     execute :rake,'db:seed'
      end
    end
  end
end

cap aborted!
