This module can only be run on a Raspberry Pi!

[louwie17]

Hi, I am using Mate 1.12.1 on my Pine 64 and get the following when trying to run my python file:

Traceback (most recent call last):
  File "./blinking_led.py", line 4, in <module>
    import RPi.GPIO as GPIO
  File "/usr/local/lib/python2.7/dist-packages/RPi/GPIO/__init__.py", line 23, in <module>
    from RPi._GPIO import *
RuntimeError: This module can only be run on a Raspberry Pi!

This is after these steps:

sudo apt-get install python-pip
sudo pip install RPi.GPIO
sudo python setup.py install

The weird thing is this worked for me before, but I had to reinstall the system, and now I keep running in to the above issue.

I managed to get it working again, switching to python3 and skipping 'sudo pip install RPi.GPIO'
Installing it with: sudo python3 setup.py install

What you experienced is expected behavior. When you did 'sudo pip install RPi.GPIO' you installed the original Rasberry Pi version of RPi.GPIO from pypi.python.org. To install the modified code that's been ported for the Pine64 you must manually install from this code repository.

I had this problem with python 2.7.
I found that I had that problem if I ran the python file inside RPi.GPIO-PineA64 folder. As soon as I moved my .py file out of that folder and it worked a charm.

Solved. Can close this issue.

i am getting this with python3 on Debian 10 for Rpi

$ python3 -V
Python 3.7.3

# uname -a
Linux rpi4-20210718 5.10.0-0.bpo.7-arm64 #1 SMP Debian 5.10.40-1~bpo10+1 (2021-06-04) aarch64 GNU/Linux

[hellresistor]

problem solved with this way ;)

 sudo apt-get purge python{,3}-rpi.gpio
 sudo pip3 install RPi.GPIO

I think problem its when people install rpi.gpio using sudo apt-get install RPi.GPIO command ;)

It seems like /proc/cpuinfo changed the structure and doesn't contain expected info anymore.
Here is the output from cat /proc/cpuinfo:

At the same time get_rpi_info function expects Hardware and Revision words

RPi.GPIO-PineA64/source/cpuinfo.c

Lines 40 to 61 in 5ee3c2f

	if ((fp = fopen("/proc/cpuinfo", "r")) == NULL)
	return -1;
	while(!feof(fp)) {
	fgets(buffer, sizeof(buffer), fp);
	sscanf(buffer, "Hardware : %s", hardware);
	if (strcmp(hardware, "BCM2708") == 0 ||
	strcmp(hardware, "BCM2709") == 0 ||
	strcmp(hardware, "BCM2835") == 0 ||
	strcmp(hardware, "BCM2836") == 0 ||
	strcmp(hardware, "BCM2837") == 0 ) {
	found = 1;
	sscanf(buffer, "Revision : %s", revision);
	} else if (strcmp(hardware, "sun50iw1p1") == 0 ||
	strcmp(hardware, "Pine64") == 0 ||
	strcmp(hardware, "Pine64+") == 0 ) {
	pinea64_found = 1;
	found = 1;
	sprintf(revision, "000b");
	} else
	sscanf(buffer, "Revision : %s", revision);
	}
	fclose(fp);

That's why the lib throws an exception here:

RPi.GPIO-PineA64/source/py_gpio.c

Lines 1023 to 1026 in 5ee3c2f

	if (get_rpi_info(&rpiinfo))
	{
	PyErr_SetString(PyExc_RuntimeError, "This module can only be run on a Raspberry Pi!");
	setup_error = 1;

This file may look differently only on my OS because I use armbian but the Raspberrypi repo has a similar issue that may be useful raspberrypi/linux#2110.

I committed your code just now. Thank you.

Beware, IIRC there were different code paths for Pine64 and Pine64+
