python - 在 centos 7 上安装 python netsnmp

Question

我收到此错误 fatal error: net-snmp/net-snmp-config.h: No such file or directory。我已经安装了 gcc、python-devel、net-snmp、net-snmp-utils、net-snmp-python 和其他开发依赖项。

CentOS Linux release 7.1.1503 (Core)

更新 1: 在 netsnmp 源目录上运行 ./configure && make && make install 后，我能够运行 python setup.py install。但是，现在我从 python 收到此错误:

>>> import netsnmp
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "netsnmp/__init__.py", line 1, in <module>
    from client import *
  File "netsnmp/client.py", line 1, in <module>
    import client_intf
ImportError: No module named client_intf
>>> 

更新 2: 我的错!!我正在从 netsnmp source dir cd/tmp/net-snmp-master/python/ 的目录运行 python 解释器，这导致我给出预期的错误，因为 python 没有使用来自 egg 的导入，而是从源头上。无论如何，在执行 cd ~ 后，我收到一个新错误

>>> import netsnmp
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "build/bdist.linux-x86_64/egg/netsnmp/__init__.py", line 1, in <module>

ImportError: libnetsnmp.so.30: cannot open shared object file: No such file or directory
>>> exit()

UPDATE4:最终通过运行 sudo ldconfig 并修改 /etc/ld.so.conf.d/libc.conf 解决了问题

[root@localhost ~]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
[root@localhost ~]# cat > /etc/ld.so.conf.d/libc.conf <<EOF
> /usr/local/lib
> EOF
[root@localhost ~]# ldconfig
[root@localhost ~]# python
>>> import netsnmp
>>> exit()
[root@localhost ~]#

确保您已经安装了 net-snmp-devel。查看/usr/include/net-snmp/net-snmp-config.h是否存在
