python – Pyro4：找不到名称服务器

概述我是 Python和Pyro4的新手.所以我尝试按照此页面 Pyro – Python Remote Objects – 4.41的第二个示例,但是当我运行服务器时抛出此异常： Traceback (most recent call last): File "greeting-server.py", line 10, in <module> ns = Pyro4.locateNS() 我是 Python和Pyro4的新手.所以我尝试按照此页面 Pyro – Python Remote Objects – 4.41的第二个示例,但是当我运行服务器时抛出此异常：

Traceback (most recent call last):  file "greeting-server.py",line 10,in <module>    ns = Pyro4.locateNS()                  # find the name server  file "/usr/lib/python2.7/dist-packages/Pyro4/naming.py",line 344,in locateNS    raise ePyro4.errors.NamingError: Failed to locate the nameserver

代码服务器：

# saved as greeting-server.pyimport Pyro4class GreetingMaker(object):    def get_fortune(self,name):        return "Hello,{0}. Here is your fortune message:\n" \               "Tomorrow's lucky number is 12345678.".format(name)daemon = Pyro4.Daemon()                # make a Pyro daemonns = Pyro4.locateNS()                  # find the name serveruri = daemon.register(GreetingMaker)   # register the greeting maker as a Pyro objectns.register("example.greeting",uri)   # register the object with a name in the name serverprint("Ready.")daemon.requestLoop()                   # start the event loop of the server to wait for calls

首先在另一个终端运行pyro-ns：

$pyro-ns*** Pyro name Server ***name server Listening on: ('0.0.0.0',9090)WARNING: daemon bound on hostname that resolves to loopback address 127.0.x.x URI is: PYRO://127.0.1.1:9090/7f0001011d2a21ca9fb63702dd216e1143URI written to: /home/guille/documents/pyro examples/Pyro4-master/examples/banks/Pyro_NS_URIname Server started.

备注：我在Debian 8上工作,我安装了：

> sudo apt-get install pyro4
> sudo apt-get install python2-pyro4
>点子安装https://pypi.python.org/packages/2.7/s/serpent/serpent-
1.7 py2.py3-NONE-any.whl

运行这个例子

也许我错过了什么.任何想法为什么这不起作用,或者我做错了什么？
提前致谢.

解决方法 这项工作对我来说：

首先在另一个终端运行python -m Pyro4.naming：

Not starting broadcast server for localhost.NS running on localhost:9090 (127.0.0.1)URI = PYRO:Pyro.nameServer@localhost:9090

而不是pyro-ns我之前为pyro4做过,因为你看到这个程序改变了
