Question

我正在尝试运行一个简单的Pyro示例（taken from this page），这是代码：

import Pyro.core
import Pyro.naming

class JokeGen(Pyro.core.ObjBase):
  def joke(self, name):
    return "Sorry "+name+", I don't know any jokes."

daemon=Pyro.core.Daemon()
ns=Pyro.naming.NameServerLocator().getNS()
daemon.useNameServer(ns)
uri=daemon.connect(JokeGen(),"jokegen")
daemon.requestLoop()

当我使用Python 2.6.5和Python 2.6.6（在Ubuntu 10.04和Debian Squeeze上都试过）运行此脚本时，我总是收到此错误：

Traceback (most recent call last):
  File "/home/ingo/tools/python/pyroserver.py", line 9, in <module>
    ns=Pyro.naming.NameServerLocator().getNS()
  File "/usr/lib/pymodules/python2.6/Pyro/naming.py", line 176, in getNS
    reply = self.sendSysCommand(NS_SYSCMD_LOCATION,host,port,trace,1,bcaddr)
  File "/usr/lib/pymodules/python2.6/Pyro/naming.py", line 76, in sendSysCommand
    raise Pyro.errors.NamingError("could not find NameServer")
Pyro.errors.NamingError: could not find NameServer

脚本有什么问题？我该如何创建该名称服务器？

Answer 1

首先在另一个终端中运行pyro-ns。那是Pyro对象经纪人。

使用NameServer启动Pyro Daemon时出错：“找不到NameServer”
