gnuradio 3.7.9.1 ImportError: No module named gnuradio

[ethicz@…]

Successfully installed gnuradio and companion working fine but having issues running python script through terminal.

ImportError: No module named gnuradio

Running OSX 10.11.4 and python 2.7. Following the troubleshooting steps mentioned in ​Ticket #28315, "ls /opt/local/lib/python2.7/site-packages" returns:

xcbgen

And "port installed | grep gnuradio" returns:

gnuradio-devel @20160331_0+docs+grc+jack+portaudio+qtgui+sdl+swig+uhd+wavelet+wxgui (active)

It appears the python modules were never installed? I appreciate the help.

In the future, please Cc the port maintainers (port info --maintainers gnuradio), if any.

The obvious question is are you using the correct python? What is the output of the following?

which python

GNU Radio's Python interface is installed for you into

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/gnuradio

You need to make sure which python returns /opt/local/bin/python; if not, you can set it via:

sudo port select python python27

HTH!

I set the python with that command, but which python now returns

/usr/local/bin/python

And trying to run the python script now still returns the import error.

Are you using HomeBrew? By default it installs into /usr/local, which we generally recommend against using because it is a standard search path for many configuration systems. We also generally recommend not using any 2 or more of HomeBrew, MacPorts, and Fink at the same time -- it's just asking for troubles (like this).

That said, if you change the PATH environment variable to have /opt/local/bin come before /usr/local/bin, that should fix this specific issue. There might be others that come up depending on what is installed in /usr/local though.

Yes I am using HomeBrew. I tried changing the path environment but couldn't get opt/local/bin to come first. I edited the .bash_profile to include this

export PATH="/opt/local/bin:$PATH"

But echo $PATH returns

/usr/bin /bin /usr/sbin /sbin /opt/local/bin /opt/local/sbin /opt/X11/bin

After you edit the .bash_profile, you either need to source it or logout & log back in (e.g., restart X11.app or XQuartz.app).

Right now, you could issue in the shell your first command (export PATH="/opt/local/bin:$PATH") and see if that works for running GR Python scripts directly.

Just had to restart, it is working now. Thank you!

Glad it's working; you're welcome; have fun!
