ruby错误解决: Address family not supported by protocol - connect(2)

ruby的socket错误：

Errno::EAFNOSUPPORT: Address family not supported by protocol - connect(2)

 

原因解析：地址集不被支持

解决方法：改成ip或者修改/etc/hosts文件

 

 

require 'socket'

include Socket::Constants

puts "*"*50

puts AF_INET

puts SOCK_STREAM

puts "*"*50

socket = Socket.new(AF_INET, SOCK_STREAM, 0)

sockaddr = Socket.pack_sockaddr_in(2202, 'localhost')         <<-- 改成127.0.0.1

 

socket.connect(sockaddr)

socket.puts "Hello from script 2."

puts "The server said, '#{socket.readline.chomp}'"

socket.close
