我正在尝试运行此示例程序 - http://pysnmp.sourceforge.net/ example/1.x/snmpbulk.html
我在 Mac OS X 上，我安装了 pysnmp -
$ sudo /usr/local/bin/pip install pysnmp
现在，当我运行该程序时，我得到 -
Traceback (most recent call last):
File "pysnmptest.py", line 2, in <module>
from pysnmp import msession
ImportError: cannot import name msession
更新：
似乎 pysnmp 4.x 没有 msession，所以我尝试了 http://pysnmp.sourceforge.net/examples/4.x /v3arch/index.html
现在我明白了 -
Traceback (most recent call last):
File "pysnmptest.py", line 2, in <module>
from pysnmp.entity.rfc3413.oneliner import cmdgen

该网页还说它们依赖于第三方库 -
最新 PySNMP 版本（4.x 及更高版本） 取决于以下因素：
Python 的 ASN.1 库用于 处理 ASN.1 对象 Python
用于 SNMP 的加密工具包 消息认证和加密
如何安装它们？直接从网页的 tarball 安装会更好吗？
I am trying to run this example program - http://pysnmp.sourceforge.net/examples/1.x/snmpbulk.html
I am on Mac OS X, and I installed pysnmp by -
$ sudo /usr/local/bin/pip install pysnmp
Now when I run the program I get -
Traceback (most recent call last):
File "pysnmptest.py", line 2, in <module>
from pysnmp import msession
ImportError: cannot import name msession
UPDATE:
seems like pysnmp 4.x doesn't have msession, so I tried http://pysnmp.sourceforge.net/examples/4.x/v3arch/index.html
and now I get -
Traceback (most recent call last):
File "pysnmptest.py", line 2, in <module>
from pysnmp.entity.rfc3413.oneliner import cmdgen
File "/Library/Python/2.6/site-packages/pysnmp/entity/rfc3413/oneliner/cmdgen.py", line 2, in <module>

from pyasn1.error import PyAsn1Error
ImportError: No module named pyasn1.error
The webpage also says they have dependencies on third-party libraries -
Latest PySNMP releases (4.x and later)
depend on the following:ASN.1 library for Python used for
handling ASN.1 objects Python
Cryptography Toolkit used for SNMP
message authentication and encryption
How do I install them? and would it better to install from the tarball from webpage directly?

您安装了哪个版本的
pysmnp？您尝试运行的示例似乎适合 1.x 版本的pysnmp。在这里我找到了最新 4的示例.x 版本。请注意，他们不使用
msession所以我猜它已被删除。编辑：看起来现在您必须从此处安装
pyasn1一个>...我不使用 OSX，所以我不知道在 OSX 上安装软件的更好方法是什么。在 ubuntu 上，我刚刚做了 apt-get install python-pysnmp ，整个东西就安装好了。
which version of
pysmnpdid you install? The example you're trying to run seems to be suited for the 1.x version ofpysnmp.Here I've found examples for the newest 4.x version. Note they don't use
msessionso I guess it was removed.EDIT: Looks like now you have to install
pyasn1from here...I don't use OSX so I don't know what's the better method for installing software on it. On ubuntu I just did
apt-get install python-pysnmpand the whole thing was installed.pyasn1已被 pysnmp 依赖。所以你只需输入：pyasn1has been depended by pysnmp. So you could just type:
