Question

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。我知道代码（python，php，只是没有rails，ruby）

所以，我试图恢复我的伙伴抛弃给我的旧项目。我已经在这里工作了12个多小时而且我已经走了很长一段路，但是我无法克服这个错误...而且我担心这个问题将会解决离开我的联盟，但我会试一试：

当我尝试启动应用程序时，出现此错误：

C：\ inetpub \ wwwroot \ Plex-Board＆gt; 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未实现，基于信号的日志重新开启不可用！ Puma以单一模式开始......

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

班级服务＆lt;的ActiveRecord :: Base的 belongs_to：service_flavor，polymorphic :: true #forest_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 开始 Timeout.timeout（@timeout）做 s = TCPSocket.new（ping_destination，self.port） S.CLOSE self.update（online_status：true，last_seen：Time.now）返回true 结束救援Errno :: ECONNREFUSED self.update（online_status：true，last_seen：Time.now）返回true 救援超时::错误，Errno :: ENETUNREACH，Errno :: EHOSTUNREACH，SocketError self.update（online_status：false）返回false 结束端

def connect_method if！self.dns_name.blank？ self.dns_name 其他 self.ip 结束结束端

我可以猜出这段代码的作用，但我不确定如何修复它，或者即使它可以修复。

Sooo，任何想法？

尝试使用rails控制台，检查此类是否已加载

Resolv::IPv4::Regex。

如果没有，则需要添加

gem 'rubysl-resolv'

在您的Gemfile中，然后捆绑安装
