Problem installing Gnuradio

Hello, everybody.

I’m having some troubles installing the Gnuradio. Everything seems all
right, but when I try to run it using the terminal, this error appears:

Traceback (most recent call last):
File “/usr/local/bin/gnuradio-companion”, line 113, in
File “/usr/local/bin/gnuradio-companion”, line 87, in main
AttributeError: ‘module’ object has no attribute ‘version’

What is it? How can I fix it? Thank you.
