Re: [pysnmp-users] PySNMP 4.3.1 strange prettyPrint() output

[Ilya E. <il...@gl...>]

To troubleshoot the MIB compilation issue I’d advise:

* Not a solution, but a quick cure: just run mibdump.py and collect compiled MIBs from where it stores them.
  I just checked, it works out-of-the-box pulling this and all required MIBs from web:

  $ mibdump.py AIRESPACE-WIRELESS-MIB

* Make sure you are running the latest version of pysmi from pypi (0.0.7)

* Enable pysmi debugging in your script and re-run your script to see where exactly it looks for MIB files:

  from pysmi import debug
  debug.setLogger(debug.Debug(‘reader'))

There’s documentation on pysmi internals, but it may be too low level in this case:
