我正在使用/ capistrano在使用capistrano进行部署时更新我的​​cron_tab,直到最近我的部署在更新cron_tab时才开始失败。

.rvm/gems/ruby-1.9.3-p362-turbo@psg-web/gems/capistrano-2.8.0/lib/capistrano/configuration/variables.rb:122:in `method_missing_with_variables': undefined method `role_names_for_host' for #<Capistrano::Configuration:0x000000018e6a10> (NoMethodError)

我正在设置* role_names_for_host *

set_default(:whenever_roles, [:workers])

我的任务看起来像这样

namespace :whenever do
  desc "Stop whenever"
  task :stop , roles: [:workers] do
    clear_crontab
  end

  desc "Start whenever"
  task :start , roles: [:workers] do
    update_crontab
  end

  desc "Restart whenever"
  task :restart , roles: [:workers] do
    update_crontab
  end

  after 'deploy:symlink', 'whenever:update_crontab'
  %w[start stop restart].each do |command|
    after "deploy:#{command}", "whenever:#{command}"
  end
end

关于我可能做错的任何想法?

宝石版

  • capistrano(2.8.0)
  • 每当(0.8.2)

1 个答案:

答案 0 :(得分:1)

在2.9.0之后的capistrano中引入了缺失的方法。

修补程序:您可以将其添加到Capfile或deploy.rb文件的顶部:

require 'capistrano/server_definition'
require 'capistrano/role'
class Capistrano::Configuration
  def role_names_for_host(host)
    roles.map {|role_name, role| role_name if role.include?(host) }.compact || []
  end
end

我建议每当更新它的gem依赖项时:)
