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 e Pyro4.errors.NamingError: Failed to locate the nameserver
代码服务器:
# saved as greeting-server.py import Pyro4 class 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 daemon ns = Pyro4.locateNS() # find the name server uri = daemon.register(GreetingMaker) # register the greeting maker as a Pyro object ns.register("example.greeting",uri) # register the object with a name in the name server print("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://127.0.1.1:9090/7f0001011d2a21ca9fb63702dd216e1143 URI written to: /home/guille/Documents/pyro examples/Pyro4-master/examples/banks/Pyro_NS_URI Name 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
