Python{2,3}: RuntimeError: This module can only be run on a Raspberry Pi! #889

Closed alexsalex closed 2 years ago

alexsalex commented 3 years ago

Hi!

Im using the retroflag case for my mediasenter. DO not use RetroPie, just like the case and safe shutdown function.

When I run safe shutdown script its shows me this error:

root@mc /opt/RetroFlag # python ./SafeShutdown.py
Traceback (most recent call last):
  File "./SafeShutdown.py", line 1, in <module>
    import RPi.GPIO as GPIO
  File "/usr/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!
root@mc /opt/RetroFlag #

All modules installed, latest version from repo. How can I fix this issue?

In this case I can't use GPIO in the Python on XBian... that is not good....

mkreisl commented 3 years ago

From where does the Python stuff came from?

alexsalex commented 3 years ago

No modifications, no updates on the system. The same issue on Python 2 and Python 3.

mkreisl commented 3 years ago

Again, from where does the Python stuff came from ?!?

/opt/RetroFlag # python ./SafeShutdown.py
...
/usr/lib/python2.7/dist-packages/RPi/GPIO/__init__.py

That's definitely no XBian software

mkreisl commented 3 years ago

I once unpacked my crystal ball

You are probably using a Raspberry Pi4 and have fetched the python-rpi.gpio library from Debian repository. Unfortunately this is the old 0.6.5 version which does not know the Pi4. I got the current 0.7 packages and added them to our repository, which should be available everywhere in 2 hours.

So a sudo apt-get update && sudo apt-get upgrade should help

That's definitely no XBian software

https://github.com/RetroFlag/retroflag-picase

Standard packages from repo: apt install python-rpi.gpio apt install python3-rpi.gpio

Update doesn't help.

Forget to mention: using XBian on Raspberry PI 4

mkreisl commented 3 years ago

If you really have the 0.7 packages installed, you have to search for the bug yourself.

This is no XBian problem and I don't have such a case, so I can't reproduce it

If you install on Raspberry PI 4 the package python-rpi.gpio, then run python:

Do you see this error?

Sure, I see it.

I did the same on my Pi4, latest kernel and I do not get this error message

I'm using XBian, nothing else

Did you read this?

https://sourceforge.net/p/raspberry-gpio-python/tickets/190/

Or if you have Pi4/8GB device read here:

https://sourceforge.net/p/raspberry-gpio-python/code/merge-requests/5/

This device seems still not be supported in official files

If I install the Rasbian (Raspberry OS) or Armbian everything is works without any issue.

Absolutely the same system with Raspbian:

I'm sure you haven't installed the 0.7 versions yet. unfortunately, i made a stupid mistake when uploading these packages, so they weren't saved correctly. Please try again in 3h, until then the correct packages are also safely distributed on the mirrors. And make sure that you really have installed the 0.7 version

I see this error on my RPi4

I had hoped that these changes had been pushed to Raspbian, but it seems not. Where can I get these patches?

@kjeldflarup you are completely wrong here. Please contact a Pi-OS aka Raspbian forum with your problem (whatever that problem is). Thanks
