I installed gnuradio. But when I want to use gnuradio-companion, I have error:

Traceback (most recent call last):
File "/usr/local/bin/gnuradio-companion", line 99, in <module>
run_main()
File "/usr/local/bin/gnuradio-companion", line 87, in run_main
from gnuradio.grc.main import main
ImportError: No module named main

How I can improve this?

Sounds like you didn't properly install it, or you somehow didn't set the `$PYTHONPATH`, or … hard to say. How did you install GNU Radio, in which version, and on which OS are you? – Marcus Müller Jul 31 '18 at 15:34
I use Ubuntu 16.04. And I install use repository: sudo apt-get install gnuradio https://wiki.gnuradio.org/index.php/InstallingGR My PYTHONPATH is ~$ echo $PYTHONPATH :/usr/local/lib/python2.7/dist-packages:/usr/local/lib/python2.7/dist-packages – Kot Leapold Aug 01 '18 at 07:23
Then you've got at least two competing installations, because the apt-get method will not install to `/usr/local`, but to `/usr/`. – Marcus Müller Aug 01 '18 at 07:31
What I must to do? – Kot Leapold Aug 01 '18 at 08:38
remember whether you've installed GNU Radio differently before? And if so, uninstall that non-apt installation. – Marcus Müller Aug 01 '18 at 09:00
The fact that you even have a pythonpath that points to /usr/local might indicated you've had a working GNU Radio installation before, or you've just done a lot of manual building of software. In any case, this is very much a problem with your own machine having remnants of multiple installations of software that are conflicting, so it's really not possible to help you any other way than recommending cleaning up your system – Marcus Müller Aug 01 '18 at 09:02
How correct clean system? How I must to delete gnuradio correct? – Kot Leapold Aug 01 '18 at 09:36
I don't know. That depends on how you've installed it. – Marcus Müller Aug 01 '18 at 10:02
I use: sudo apt-get install gnuradio – Kot Leapold Aug 01 '18 at 12:52
no, you used something else before, and have a second installation in /usr/local. – Marcus Müller Aug 01 '18 at 12:53
Can I delete /usr/local correct – Kot Leapold Aug 01 '18 at 13:05
I DON'T KNOW. It's your system. – Marcus Müller Aug 01 '18 at 13:12
Synaptic has an easy to install and stable version – ijuneja Aug 03 '18 at 13:49
