Maybe wrong target dir?

[motom001]

I use bananian and follow the install instructions.

1st: apt-get install gcc is missing
2nd: there is no sudo for bananian

The setup install to /usr/local/lib/python2.7/dist-packages but all other packages are located under /usr/lib/python2.7/dist-packages

@motom001:
I compiled the module for Python 3, but that should be the same:

# python3
Python 3.2.3 (default, Feb 20 2013, 22:32:37) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import RPi.GPIO as GPIO
BAPI: revision(1)
>>> 

Module's name is RPi.GPIO (without _BP).

I hope this can help you.

Ciao!

I have the same problem. Using correct "import RPi.GPIO as GPIO" still produces the above mentioned error on bananian.

[PA0MHE]

I have the same problem as motom001, only I'm using a bananapi (not the pro)
Is it possible to manually move the files to the other directory ?? Or do I need to do more ?

[paramono]

Make sure the module is installed by running:

pip freeze  # substitute pip for pip3 if necessary

If it is, then check your current working directory (pwd). If you're still inside the RPi.GPIO_BP source directory, cd somewhere else, and run python from there - the error should disappear.

I created a pull request where I updated readme file with this information. Hope it helps.
