PI FACE cant import module into Python

Are you sure that the piface directory with all the stuff has been created in your home directory?

I think there is an error in the install.txt script that you are told to download by the PiFace documentation.

(wget http://oi.cs.man.ac.uk/download/install.txt)

Open the file with an editor (like nano) and change the line

pushd ~/

to

pushd   (i.e. remove the ~/ ).

Now execute the wget http://oi.cs.man.ac.uk/download/install.txt  and check if the piface directory has been created.

I too have the same problem. I have tried twice - from the ground up with a clean installation of the latest Raspbian (and updates) then followed the install process to the letter. Bizzarely the piface emulator works - leds come on, relays switch etc. Try to to the "import piface.pfio as" and you get the "ImportError: No Module named piface.pfio".

I'm at a loss as what to do now...

I have even manually ensure that the various scripts did what they were supposed to e.g. add pi to the spi groups etc.

Weird.

Can anyone help please?

Update:

Ah Ha!

I tried running the ~/piface/python/test/piface_test.py script (as sudo) and it worked. I did a ls -l on the file and it was owner:root group:root so i chown and chgrp my effort to the same and ran it (as sudo) and it worked!!!!!!!!!!!

Yahoo...

Now - how to fix this so that I can run everything as user pi? because I edited the priveledges I can no longer use IDLE3 to edit the file (i now must use sudo vi).

Ok - the "ImportError: No module name piface.pfio" is permissions related - so how to fix...

?

Help appreciated.

Further Update:

I resistalled Raspbian from scratch + updates.

Ran the installation process - thinking I may have run it as sudo last time(s).

Same problem - won't load but will if i change to chown my file.py to root.

This is dumb - is this happening to anyone else?

Try this:

in the install.txt file replace

pushd ~/

by this:

pushd

I am very new to this, only getting my Pi and Piface last week, so I applogise if my thoughts are incorrect.

I have the same problem. "ImportError: No Module named piface.pfio" when trying to use IDLE3 or IDLE

However if I create some simple test code for the PiFace Board and run my test program directly through TerminalTX by changing the directory to Pi/PiFace/Python/Test  ie (python MyTest.py) then it works correctly, so I assume the piface profile can be loaded from where ever 'Python' calls it using TerminalTX in the code source directory.

So I guess it must be some kind of path issue when trying to run the code using IDLE3 as it will use a different directory location which my not have access to the piface.pfio

I also changed the install.txt as above from pushd ~/ to pushd, restarted my Pi but still same problem, should I re-download the software package PiFace Software (wget http://pi cs.man ac.uk/download/install.txt) and then run the 'hash install.txt' again OR just re-run the 'hash install.txt again with the modified install.txt.

If anyone has any thoughts as to what the problem is then I would be very greatfull.
