unable to execute new installation

I have installed the latest version of GNU Radio from source. When I tried to execute from the RPi GUI nothing happened. I then tried the following execution:

 

pi@raspberrypi:~ $ cd gnuradio/grc/scripts

pi@raspberrypi:~/gnuradio/grc/scripts $ ls

CMakeLists.txt  freedesktop  gnuradio-companion  grcc

pi@raspberrypi:~/gnuradio/grc/scripts $ python3 gnuradio-companion

Running from source tree

Could not retrieve GNU Radio configuration directory from GNU Radio. Trying defaults.

Could not retrieve GNU Radio persistent state directory from GNU Radio. Trying defaults.

Traceback (most recent call last):

  File "/home/pi/gnuradio/grc/main.py", line 229, in get_state_directory

    from gnuradio.gr import paths

ImportError: cannot import name 'paths' from 'gnuradio.gr' (/usr/lib/python3/dist-packages/gnuradio/gr/__init__.py)

 

During handling of the above exception, another exception occurred:

 

Traceback (most recent call last):

  File "/home/pi/gnuradio/grc/scripts/gnuradio-companion", line 103, in <module>

    run_main()

  File "/home/pi/gnuradio/grc/scripts/gnuradio-companion", line 96, in run_main

    sys.exit(main())

  File "/home/pi/gnuradio/grc/main.py", line 297, in main

    log_file = os.path.join(get_state_directory(), "grc.log")

  File "/home/pi/gnuradio/grc/main.py", line 250, in get_state_directory

    f"files to '{newpath}'.")

UnboundLocalError: local variable 'newpath' referenced before assignment

 

What do I need to do?
