在 Python 中未找到 RPi.GPIO

Question

I am trying to get the GPIO module working on a Raspberry Pi 3B+. I have installed the libraries as below. It works fine in Python2 but not Python 3 (version 3.9). Any ideas would be appreciated.

pi@raspberrypi:/usr/bin $ sudo apt-get install python-rpi.gpio python3-rpi.gpio

You should run the following command in the terminal to install the RPi module which contains GPIO : pip3 install rpi-gpio

These commands will download and install the RPi module.
