Re: [Discuss-gnuradio] ModuleNotFoundError

[Ron Economos]

The PYTHONPATH should be:

/usr/local/lib/python3.7/dist-packages

The LD_LIBRARY_PATH should be:

/usr/local/lib

A couple more notes. Make sure you do a sudo ldconfig after the build. 
Also, there was a bug in the 3.8.0.0-rc1 tag. Make sure you build the 
latest 3.8.0.0-rc2 tag (or anything after commit 0ab6a74).
