RPi.GPIOを使いたい。

環境

2020-12-02-raspios-buster-armhf-lite.zip


pi@raspberrypi:~ $ cat /etc/issue
Raspbian GNU/Linux 10 \n \l

Python2 なら使えるが

$ python
Python 2.7.16 (default, Oct 10 2019, 22:02:15) 
[GCC 8.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import RPi.GPIO as GPIO

Python3 だと使えないので


pi@raspberrypi:~ $ python3
Python 3.7.3 (default, Jul 25 2020, 13:03:44) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import RPi.GPIO as GPIO
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'RPi'

まず PIP3 をレポジトリからインストール


$ sudo apt install python3-pip
