[Discuss-gnuradio] installing gnuradio using pybombs

I am trying to install gnu radio using pybombs. However, I got the following error:

PyBOMBS - INFO - PyBOMBS Version 2.3.2

PyBOMBS.auto-config - INFO - Using config file: None

Traceback (most recent call last):

AssertionError

Any advice on how to fix the problem would be appreciated.
