Actually, not reporting a PYTHONPATH is an error.
In order for the gnuradio-companion to find osmosdr/_osmosdr_swig.so it
needs a PYTHONPATH defined - there's more than version of python
installed on most Linux systems.
Try it again but type
python2.7 -c "import os; print(os.environ.get('PYTHONPATH', ''))"
It's possible that python is linked to a different version of python2.7
on your system.
If it's empty again, make sure python2.7 is the version of python you're
using in your shell by typing
python --version
If the version is not python2.7 (or a minor version of 2.7) then add
alias python="/usr/bin/python2.7"
to your $HOME/.bashrc file.
And add then
export PYTHONPATH="/usr/lib64/python2.7/site-packages"
to your $HOME/.bashrc
Then finally, type
. $HOME/.bashrc
There's a "period" in front of $HOME/.bashrc - it may be hard to see -
it means source the file $HOME/.bashrc - which will set your PYTHONPATH
environment variable.
Then try to to startup up gnuradio-companion again.
