Question

我在这篇文章中可以看到类似的问题https://github.com/fgimian/easysnmp/issues/42 但我不确定同样的问题是否适用于我。

基本上我已经通过home-brew安装了python

alexs-mbp:~ alex$ which python
/usr/local/bin/python
alexs-mbp:~ alex$

并通过pip和net-snmp通过home-brew安装easysnmp

alexs-mbp:~alex$ python
Python 2.7.13 (default, Dec 18 2016, 07:03:39)

>>> import easysnmp

使用brew检查时，我也收到此消息

 Warning: net-snmp is a keg-only and another version is linked to opt.
Use `brew install --force` if you want to install this version
alexs-mbp:~ alex$ brew install net-snmp --force
Warning: net-snmp-5.7.3 already installed, it's just not linked.
alexs-mbp:~ alex$

我做了一个brew链接，它给了我以下

Warning: net-snmp is a keg-only and another version is linked to opt.
Use `brew install --force` if you want to install this version
alexs-mbp:~ alex$ brew install net-snmp --force
Warning: net-snmp-5.7.3 already installed, it's just not linked.
alexs-mbp:~ alex$ brew link net-snmp
Warning: net-snmp is keg-only and must be linked with --force
Note that doing so can interfere with building software.

If you need to have this software first in your PATH instead consider running:
  echo 'export PATH="/usr/local/opt/net-snmp/bin:$PATH"' >> ~/.bash_profile
  echo 'export PATH="/usr/local/opt/net-snmp/sbin:$PATH"' >> ~/.bash_profile
alexs-mbp:~ alexwilloughby$ brew link net-snmp --force
Linking /usr/local/Cellar/net-snmp/5.7.3... 182 symlinks created

If you need to have this software first in your PATH instead consider running:
  echo 'export PATH="/usr/local/opt/net-snmp/bin:$PATH"' >> ~/.bash_profile
  echo 'export PATH="/usr/local/opt/net-snmp/sbin:$PATH"' >> ~/.bash_profile
alexs-mbp:~ alex$

启动python并导入easysnmp仍然给我同样的错误有谁知道如何解决这个问题？

问题似乎源于net-snmp的自制安装与easysnmp的pip安装的不兼容性。尝试卸载easysnmp并从此fork https://github.com/kamakazikamikaze/easysnmp重新安装：

pip uninstall easysnmp
pip install git+https://github.com/kamakazikamikaze/easysnmp.git
