Experts:
您好！
my ifinger.tac file content like following:
fromtwisted.applicationimportinternet,
servicefromtwisted.internetimportprotocol, reactor,
deferfromtwisted.protocolsimportbasicclassFingerProtocol(basic.LineReceiver):
deflineReceived(self, user):
d = self.factory.getUser(user)
defonError(err):
return'Internal error in server'd.addErrback(onError)
defwriteResponse(message):
self.transport.write(message + '\r\n')
self.transport.loseConnection()
d.addCallback(writeResponse)
classFingerFactory(protocol.ServerFactory):
protocol = FingerProtocoldef__init__(self, **kwargs):
self.users = kwargsdefgetUser(self, user):
returndefer.succeed(self.users.get(user, "No such user"))
application = service.Application('finger', uid=1, gid=1)
factory = FingerFactory(moshez='Happy and well')
internet.TCPServer(79,
factory).setServiceParent(service.IServiceCollection(application))
when running this script with command-line : twistd -y ifinger.tac, error
occurs like :
Traceback (most recent call last):
File "/usr/local/bin/twistd", line 7, in <module>
import _preamble
ImportError: No module named '_preamble'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/local/bin/twistd", line 9, in <module>
sys.exc_clear()
AttributeError: 'module' object has no attribute 'exc_clear'
And i run python3 in interactive mode to check if exc_clear method is defined
in sys, command line like :
>>>import sys
>>>sys.__dict__["exc_clear"]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
sys.exc_clear()
KeyError: 'exc_clear'
>>>
Is there any configuration i should do ? please help to give me an answer.
谢谢！！
