Question

我安装了Anaconda2.5，它给了我Python 2.7。我安装了最新的PySNMP。最初，我尝试使用Python 2.6在另一台服务器上运行Python脚本并获得TypeError（见下文）。我认为一定是因为我的Python版本，可能是PySNMP改变了一些东西，但是当我运行他们的示例代码（见下文）时，它返回了完全相同的错误。我很困惑为什么他们的示例代码会返回错误并且只能怀疑Anaconda安装PySNMP会出错？
这是示例代码：

#!/root/anaconda2/python

from pysnmp.hlapi import *

for (errorIndication,
     errorStatus,
     errorIndex,
     varBinds) in nextCmd(SnmpEngine(),
                      CommunityData('public', mpModel=0),
                      UdpTransportTarget(('demo.snmplabs.com', 161)),
                      ContextData(),
                      ObjectType(ObjectIdentity('IF-MIB', 'ifDescr')),
                      ObjectType(ObjectIdentity('IF-MIB', 'ifType')),
                      ObjectType(ObjectIdentity('IF-MIB', 'ifMtu')),
                      ObjectType(ObjectIdentity('IF-MIB', 'ifSpeed')),
                      ObjectType(ObjectIdentity('IF-MIB', 'ifPhysAddress')),
                      ObjectType(ObjectIdentity('IF-MIB', 'ifType')),
                      lexicographicMode=False):

if errorIndication:
    print(errorIndication)
    break
elif errorStatus:
    print('%s at %s' % (errorStatus.prettyPrint(),
                        errorIndex and varBinds[int(errorIndex)-1][0] or '?'))
    break
else:
    for varBind in varBinds:
        print(' = '.join([x.prettyPrint() for x in varBind]))

这是我的错误：

它必须与不兼容的pysnmp / pyasn1版本有关。

根据您的情况，您可能希望将两个软件包推送到最新的PyPI版本（pip install --upgrade pysnmp pyasn1），或者，如果您遇到当前的pyasn1版本，请将pysnmp降级到4.3.10。

即使使用示例代码，PySNMP也会使用Anaconda安装返回TypeError
