PYSNMP:TypeError:setComponentByType()获取关键字参数'verifyConstraints'的多个值

Question

面对PYSNMP 4.3.3的新问题.Python 2.7.13.With SNMP GET和Getnext:与Pysnmp 4.3.2一样正常.实际上我正在观察它与虚拟环境有关的问题.在虚拟环境中,即使我将Pysnmp从4.3.3降级到4.3.2,问题也会被重现.

有人可以告诉我我错过了什么吗？

TypeError:setComponentByType()获取关键字参数'verifyConstraints'的多个值

>>> from pysnmp.hlapi import *
>>> errorIndication, errorStatus, errorIndex, varBinds = next(
...     getCmd(SnmpEngine(),
...            CommunityData('public'),
...            UdpTransportTarget(('127.0.0.1', 161)),
...            ContextData(),
...            ObjectType(ObjectIdentity('SNMPv2-MIB','sysDescr', 0)))
... )

与旧款式也一样:

>>> from pysnmp.entity.rfc3413.oneliner import cmdgen
>>> cmdGen = cmdgen.CommandGenerator()
>>> errorIndication, errorStatus, errorIndex, varBindTable = cmdGen.nextCmd(cmdgen.CommunityData('public'),cmdgen.UdpTransportTarget(('127.0.0.1', 161), timeout=60, retries=3),cmdgen.MibVariable('SNMPv2-MIB','sysDescr',0))

使用的包:

appdirs==1.4.2
packaging==16.8
ply==3.10
pyasn1==0.2.3
pycryptodome==3.4.5
pyparsing==2.1.10
pysmi==0.0.7
pysnmp==4.3.3
six==1.10.0

++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++ 从pyasn1 == 0.2.3将Pyasn1降级到0.1.9后,++++++似乎代码正常工作.但问题是在Pysnmp 4.3.3全新安装的同时,Pyasn1 == 0.2.3并且失败了.

Answer 1

这是pyasn1/pysnmp交互中的一个不幸的回归.

您可以通过将pyasn1降级到0.2.2或从git master获取pysnmp 或稍等一下直到修复pysnmp出来来解决这个问题.
