gnuradio @3.7.5.1_0+docs+grc+jack+orc+portaudio+python27+qtgui+sdl+swig+uhd+wavelet+wxgui ImportError at launch of Gnuradio-companion

[patrickmccanna@…]

I recently updated to 10.9.5 and tried to get gnuradio properly working for use with a HackRF.

Gnuradio-companion crashes out with the following error:

./gnuradio-companion

Please remove the software you have installed in /usr/local. Having software installed there can confuse MacPorts. After removing it, you may need to rebuild affected MacPorts ports.

I'll second what Ryan wrote, and add: I'm not sure why Python is picking up /usr/local's install of Python, unless you have set the PYTHONPATH to include that before /opt/local, or maybe you're using Python from within /usr/local. It's generally not wise to have software installed in /usr/local that is duplicated in /opt/local ... so, removing the duplicated parts would be wise; or, just removing all of /usr/local if you can. That said, if you use MacPorts' Python (/opt/local/bin/python2.7) and make sure no /usr/local is in the PYTHONPATH, then you're probably OK ... worth a try before reinstalling everything. If it fails, then I think you're better off trying what Ryan wrote.

My pythonpath is only "/usr/local/lib/python2.7/site-packages", so your comment seems right on. I'll update and report back.

/usr/local/bin is used by Docker. Is this likely to be a potential conflict for docker & gnuradio users in the future?

Updating the path worked. Thank you gents!

You're welcome; thanks for reporting back! I'm not familiar with Docker, so I can't say whether there will be future issues. In looking through the Docker website, it looks like you might not need to set PYTHONPATH at all to use it; just PATH (with /usr/local/bin in it). Anyway, I'm glad we got this issue understood. Good luck!
