Type $PYTHONPATH in bash what does it return? Also from the Python interpreter (type python in bash), type
import sys sys.path What does this return? They should return things like /usr/lib64 (and lib)/python2.7/site-packages and /usr/local/lib64 (and lib)/python2.7/site-packages. So what python does when it looks for a module to import, it looks in those folders defined by pythonpath and sys.path. If you want to import a package that's called rtlsdr, there should be a folder in one of the site-packages folders called rtlsdr. Additionally in that folder there should be a __init__.py file. That's how finding modules works in a nutshell. If you didn't have a PYTHONPATH, type this into a bash prompt to set one (it will set for that user only) export 1 >> $PYTHONPATH=/usr/local/lib64/python2.7/site-packages reference: http://docs.python.org/tutorial/modules.html On Wed, Jun 6, 2012 at 11:28 PM, Phil <phil_...@bigpond.com> wrote: > I'm almost afraid to ask such a basic question.
