No module PowerNet-MIB loaded

I can't seem to get this working, installed with pip3 install -r requirements.txt and python3 setup.py install on Debian 10:

# check_ups_apc -C asd -H 12.16.0.5 -vvv
UPSAPC UNKNOWN: pysnmp.smi.error.MibNotFoundError: No module PowerNet-MIB loaded at <pysnmp.smi.builder.MibBuilder object at 0x7f35e64abcc0>caused by <class 'ValueError'>: invalid literal for int() with base 10: 'PowerNet-MIB::upsBasicIdentModel'

During handling of the above exception, another exception occurred:

Starting SNMP polling of host 12.16.0.5 

If I forcibly load PowerNet-MIB:

class UPSAPC(nagiosplugin.Resource):  # pylint: disable=too-few-public-methods
        def __init__(self, args):
                self.args = args
                ups_apc_snmp.snmpclient.add_mib_path(MIB_PATH)
+                ups_apc_snmp.snmpclient.load_mibs('PowerNet-MIB')
                self.snmpclient = None

there is no error at this point of loading, but it still continues to give the same error including "No module PowerNet-MIB loaded".

Unfortunately I'm not familiar enough with Python and pysnmp to figure out how to fix this, any ideas?

Thanks -davidc

We always use the Debian package. The Debian package is building the python modules without zipping the contents (Python egg). pysnmp cannot access the corresponding MIB file, if the python module is zipped. Adding a zip_safe=False fixes this issue for manual source installs

Solved, thank you.
