PySNMP Error: pysnmp.smi.error.SmiError

Question

I am running a Python program on a Windows XP machine. When I run the program, I get the following error:

File "C:\Python27\lib\pysnmp\smi\builder.pyt, line 230, in loadModules...
pysnmp.smi.error.SmiError: MIB file "SNMPv2-MIB.py[co]" not found in search path

The file SNMPv2-MIB.py is currently located in C:\Python27\Lib\pysnmp\smi\mibs. Does anyone know how I can solve this?

Answer 1

if a mib is missing make sure you have performed a pip install pysnmp-mibs first if you used pip install pysnmp.

Answer 2

I just ran into the same issue. I filed a bug for it and included a patch: https://sourceforge.net/tracker/?func=detail&aid=3204704&group_id=14735&atid=114735

As Sivakumar says, the reason it's failing is because pysnmp is looking for MIBs with a .pyc or .pyw extension. pysnmp gets these extensions from imp.get_suffixes(). Based on the way pysnmp deals with the extensions returned from this function, the .pyw entry will overwrite the .py entry. The fix I proposed will simply ignore the .pyw extension.

If you install the library from the .egg it should work fine because the .egg includes compiled (pyc) MIBs.
