解决树莓派中python3无法import模块RPi.GPIO的问题办法

pi@raspberrypi:~ $ python3
Python 3.6.4 (default, Apr  8 2018, 18:42:32) 
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import GPIO
Traceback (most recent call last):
  File "", line 1, in

ModuleNotFoundError: No module named 'GPIO'

显示python3里面没有RPi.GPIO，但是python2.7里面有

pi@raspberrypi:~/GPIOtest $ python 
Python 2.7.13 (default, Jan 19 2017, 14:48:08) 
[GCC 6.3.0 20170124] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import RPi.GPIO

>>> 

思来想去，还是pip来安装吧

pi@raspberrypi:~/GPIOtest $ sudo pip3 install RPi.GPIO
Collecting RPi.GPIO
  Downloading RPi.GPIO-0.6.3.tar.gz
Installing collected packages: RPi.GPIO
  Running setup.py install for RPi.GPIO ... done

Successfully installed RPi.GPIO-0.6.3
