I find out that different version of Ryu has different name of bytearray_to_hex.
In older version, it is bytearray_to_hex, while in newer version, it is
_bytearray_to_hex.
so, the problem now is that how to build Ryu completely?

????: [Ryu-devel] utils module has not attribute bytearray_to_hex
If errors occur when parsing a packet, Ryu will raise a except, which will call
utils.bytearray_to_hex method.
Unfortunately, it will raise an attribute ERROR: 'module' utils has not
attribute 'bytearray_to_hex'
but I still can find the bytearray_to_hex method in utils.py
Why?
Related codes show below:
try:
return msg_parser(datapath, version, msg_type, msg_len, xid, buf)
except:
LOG.exception(
'Encounter an error during parsing OpenFlow packet from switch.'
'This implies switch sending a malformed OpenFlow packet.'
'version 0x%02x msg_type %d msg_len %d xid %d buf %s',
version, msg_type, msg_len, xid, utils.bytearray_to_hex(buf))
return None
