使用 Windows 10E ruby​​ 2.3.3p222（2016-11-21 修订版 56859）[i386-mingw32] puma v 2.13.4

我是一个巨大的 PUMA 菜鸟，所以请原谅我。我知道代码（python、php，只是不知道 rails、ruby）

因此，我正在尝试恢复我的好友倾倒给我的旧项目。我已经为此工作了 12 多个小时，我已经走了很长一段路，但我无法克服这个错误......我担心这个决议会超出我的范围，但我试一试：

当我尝试启动应用程序时，我收到此错误：

C:\inetpub\wwwroot\Plex-Board>sh runserver.sh * SIGUSR2 未实现，基于信号的重启不可用！* SIGUSR1 未实现，基于信号的重启不可用！*** SIGHUP 未实施，基于信号的日志重新打开不可用！彪马以单一模式启动...

有问题的文件（C：/inetpub/wwwroot/Plex-Board/app/models/service.rb）中有这一行：

class Service < ActiveRecord::Base belongs_to :service_flavor, polymorphic: :true # before_destroy :destroy_associated after_initialize :init

attr_accessor :timeout
strip_attributes only: [:ip, :url, :dns_name], collapse_spaces: true

validates_associated :service_flavor
validates :name, presence: true, uniqueness: true, allow_blank: false
validates :url, presence: true, uniqueness: true, allow_blank: false
validates_inclusion_of :port, in: 1..65535
validates :ip, length: { minimum: 7, maximum: 45 },
    format: { with: Resolv::IPv4::Regex },
    uniqueness: { scope: :port }, allow_blank: true
validates :dns_name, length: { minimum: 2, maximum: 127 },
    uniqueness: { scope: :port }, allow_blank: true
validates :ip, presence: true, if: (:ip_and_dns_name_dont_exist)
validates :dns_name, presence: true, if: (:ip_and_dns_name_dont_exist)

def init
  @timeout ||= 5
  self.online_status ||= false
end

def ip_and_dns_name_dont_exist
    if (ip.blank? || ip.to_s.empty?) && (dns_name.blank? || dns_name.to_s.empty?)
        self.errors.add(:base, 'IP Address or DNS Name must exist')
        true
    else
        false
    end
end

def ping ping_destination = connect_method begin Timeout.timeout(@timeout) do s = TCPSocket.new(ping_destination, self.port) s.close self.update(online_status: true, last_seen: Time.now) return true end rescue Errno:: ECONNREFUSED self.update(online_status: true, last_seen: Time.now) return true rescue Timeout::Error, Errno::ENETUNREACH, Errno::EHOSTUNREACH, SocketError self.update(online_status: false) return false end end

def connect_method if !self.dns_name.blank? self.dns_name else self.ip end end end

我可以猜到这段代码的作用，但我不确定如何修复它，或者即使可以修复。

苏，有什么想法吗？

尝试在 rails 控制台中，检查此类是否已加载

Resolv::IPv4::Regex.

如果没有，那么您应该需要添加

gem 'rubysl-resolv'

在您的 Gemfile 中，然后捆绑安装
