gtk.GtkWarning: could not open display

[sergioymar]

Hello everyone, I made the installation from the bash console in windows 10 using ubuntu 16.04 following the instructions and when opening the gnuradio-companion file I get the following errors:

Traceback (most recent call last): File "/usr/local/bin/gnuradio-companion", line 97, in check_gtk() File "/usr/local/bin/gnuradio-companion", line 64, in check_gtk die(err, "Failed to initialize GTK. If you are running over ssh, " File "/usr/local/bin/gnuradio-companion", line 42, in die import gtk File "/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/init.py", line 69, in _init() File "/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/init.py", line 57, in _init warnings.warn(str(e), _gtk.Warning) gtk.GtkWarning: could not open display

Could someone tell me how to fix this error?

Thank you very much in advance and a very cordial greeting for all.
