PYSNMP：TypeError：setComponentByType（）获得关键字参数'verifyConstraints'的多个值

面临PYSNMP 4.3.3的新问题。 Python 2.7.13.使用SNMP GET和Getnext：与Pysnmp 4.3.2一样正常工作。这个问题实际上我在观察它涉及到虚拟环境时。在虚拟环境中，即使我将Pysnmp从4.3.3降级到4.3.2，问题也得到转载。PYSNMP：TypeError：setComponentByType（）获得关键字参数'verifyConstraints'的多个值

有人能告诉我我失踪了什么吗？

类型错误：setComponentByType（）得到了关键字参数多个值 'verifyConstraints'

>>> 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))) 
...)

随着老款也一样：

>>> 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))

包使用：

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

++++++++++++++++++++++++++++++++++ +++++++++++++++++++++++++++++++++++++++++++ 更新： +++ ++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++似乎从pyasn1 == 0.2.3降级Pyasn1到0.1.9后的代码工作如常。但问题是，新鲜安装Pysnmp 4.3.3它采取Pyasn1 == 0.2.3及其失败。

这是在pyasn1/pysnmp互动不幸的回归。

你可以修复由要么降级pyasn1到0.2.2或git master采取pysnmp或等待一点点，直到固定pysnmp出来。

@illya Etingof非常感谢您的帮助，我们将等待修复并使用0.2.2。 – sbhatta
