Hi, I have tried the steps indicated for Raspbian OS, and almost everything works fine... except the read_fan_speed.py script. It returns:

Traceback (most recent call last):
File "./read_fan_speed.py", line 4, in <module>
import RPi.GPIO as GPIO
ImportError: No module named RPi.GPIO

I have these packages installes, as per instructions in wiki:
pigpio python-pigpio python3-pigpio

I also tried to install:
python-rpi.gpio
but got this message from apt:
"Package python-rpi.gpio is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source"

If i do: "dpkg -l | grep gpio" I get this:

ii libpigpio-dev
ii libpigpio1
ii libpigpiod-if-dev
ii libpigpiod-if1
ii libpigpiod-if2-1
ii pigpio
ii pigpio-tools
ii pigpiod
ii python-pigpio
ii python3-gpiozero
ii python3-pigpio
ii python3-rpi.gpio
ii raspi-gpio
ii rpi.gpio-common:armhf

python -V returns this:
Python 2.7.18
(I guess it's all right, as read_fan_speed is a python-2 script)

I don't have pip nor pip3 installed, and I don't know how to install them, in case it's needed to further install something else...
I have search in lots of python forums, but none of the solutions proposed worked.

What am I doing wrong? Any ideas?

Thanks a lot,
