automatic.py doesn't detect (installed) RPi module #96

Closed dchmelik closed 2 years ago

dchmelik commented 3 years ago

On Slackware ARM for Raspberry Pi (SARPi) current version, automatic.py doesn't detect (installed) RPi module:

root@1.darwinheim:~/fanshim-python/examples# pip3 install RPi
Requirement already satisfied: RPi in /usr/lib/python3.9/site-packages (0.0.1)
root@1.darwinheim:~/fanshim-python/examples# ./automatic.py
Traceback (most recent call last):
  File "/root/fanshim-python/examples/./automatic.py", line 2, in <module>
    from fanshim import FanShim
  File "/usr/lib/python3.9/site-packages/fanshim/__init__.py", line 1, in <module>
    import RPi.GPIO as GPI
ModuleNotFoundError: No module named 'RPi'

Perhaps it depends on something else? Older programmers have called Python a mess of dependencies; is there a dependency list? On another topic, I use my RPi with a HighPi case (has room for a hat) and serial port hat but want to put the fan underneath it but couldn't find anything called 'booster header'... what should I use for that, exactly, or maybe the serial port hat doesn't need to be all the way on the pins? If it does, I'm unsure both will fit...

Sorry I'm probably far too late to be of any use here, but I suspect "pip3" is probably referring to a version of python other than the "python3" that Fan SHIM uses. This could be because you have multiple versions of Python 3 installed, or still running in a virtual environment, or some other mystery meat quirk of Python.

I tend to be explicit with: python3 -m pip install rpi.gpio to avoid this, but... yeah Python is still a nightmare :grimacing:

There neither were multiple Python 3 (though has Python 2) nor virtualization. However your longer command worked.
