Cygwin Python Import Error

Dear Sir:

Hi, I am install gnuradio with cygwin on the vista.

In the /usr/src/gnuradio-3.1.1/gnuradio-examples/python, I want to
choose
any example to run test.

So, that into the /audio, and type command: $python audio_fft.py

I gat a result:

Traceback (most recent call last):

File “audio_fft.py”, line 23, in

From gnuradio import gr, gru, audio

ImportError: No module named gnuradio

I am a beginner to learning gnuradio and python, that maybe a stupid
question. But I just don’t know.

Who can help me, I am appreciation.

ImportError: No module named gnuradio
Is there a “gnuradio” directory in
/usr/local/lib/python2.5/site-packages?
(There should be.)

Did you set your PYTHONPATH environment variable to
/usr/local/lib/python2.5/site-packages? (You should have.)
