Re: [Discuss-gnuradio] Import Error

[Ben Gelb]

I'm away from my machine with GnuRadio right now so I can't 
double-check, but I think you need to set the PYTHONPATH environment 
variable.

I installed gnuradio to /usr/local/gnuradio so if I recall correctly, I run

export PYTHONPATH=/usr/local/gnuradio/python

If that doesn't work, its in one of the README files, which should 
explain what to set this variable to.
