PYSNMP 4.4.12无法编译自定义MIB

Question

在我第一次尝试pysnmp时，我正在努力加载自定义MIB。我已经读到，旧版本需要编译自定义MIB，而新版本将编译嵌入后端进程。当我尝试任何一种方法时，脚本都会挂起。。。无限期地自定义MIB是我下载的CISCO-PRODUCTS.MIB，以.my扩展名结尾

python3 mibdump.py  --mib-source=file://./ --destination-directory=/home/myuser/Desktop/Ansible/mibs --destination-format=pysnmp  CISCO-PRODUCTS-MIB

Source MIB repositories: file://./  Borrow missing/failed MIBs from:
http://mibs.snmplabs.com/pysnmp/notexts/@mib@  
Existing/compiled MIB locations: pysnmp.smi.mibs, pysnmp_mibs  
Compiled MIBs destination directory: /home/myuser/Desktop/Ansible/mibs

MIBs to compile: CISCO-PRODUCTS-MIB  
Destination format: pysnmp  
Parser grammar cache directory: not used  
Also compile all relevant MIBs: yes  
Rebuild MIBs regardless of age: no  
Dry run mode: no  
Create/update MIBs: yes  
Byte-compile Python modules: yes (optimization level no)  
Ignore compilation errors: no

同一目录中的文件包括：

• CISCO-PRODUCTS-MIB.my
• CISCO-SMI.my
• mibdump.py
• SNMPv2-CONF.my
• SNMPv2-SMI.my
• SNMPv2-TC.my

有人知道错误在哪里吗

添加 mib-searcher参数可以解决问题`

mibdump.py  disable-fuzzy-source  mib-source /home/user/.snmp/mibs  mib-searcher=/home/user/.snmp/mibs  destination-format pysnmp [MIB_ MODULE]

其中[MIB_MODULE].MIB文件显示在/home/user/.snmp/mibs目录中
