Unable to debug Qt application

[jigarp]

Hello

I'm using Qt for cross compiling am335x processor with linux kernel 4.9.28 on ubuntu 16.04.
I'm unable to debug my linux application using Qt creator 4.0.2 based on Qt 5.7.0.
while trying to debug it shows this as output
Debugging starts
Listening on port 10000
Debugging has failed

Here i'm posting my debug log last lines

Looks like Python import error. Try installing the json module via pip, perhaps?

And definitely update your Qt Creator to newest version.
