ruby - SocketError：sockaddr 解析为多个节点名

Question

在 ruby​​ 代码段失败后，删除此代码段未显示任何错误。我看到已关闭的问题https://bugs.ruby-lang.org/issues/15067，它们是否相同。此代码段上的任何输入都将非常有用。

platform_is_not :windows do
        describe 'using NI_NUMERICHOST as the flag' do
          it 'returns an Array containing the numeric hostname and service name' do
            Socket.getnameinfo(@addr, Socket::NI_NUMERICHOST).should == [ip_address, 'ftp']
          end
        end
      end

有错误

Socket.getnameinfo using IPv4 using a 3 element Array as the first argument using NI_NUMERICHOST as the flag returns an Array containing the numeric hostname and service name ERROR
SocketError: sockaddr resolved to multiple nodename
