NanoPi NEO4にWiringPi-Python for RK3399をインストール

インストールされているPythonのバージョンを確認。Python2，Python3の両方がインストールされている。

pi@NanoPi-NEO4:~$ python --version
Python 2.7.15+
pi@NanoPi-NEO4:~$ python3 --version
Python 3.6.8

とりあえず、Python3用のものをインストール

WiringPi-Python for RK3399 - FriendlyARM WiKi

cd /var/tmp/
sudo apt install git python-dev python-setuptools python3-dev python3-setuptools swig
apt install git python-dev python-setuptools python3-dev python3-setuptools swig
wget https://pypi.io/packages/source/s/setuptools/setuptools-33.1.1.zip
unzip setuptools-33.1.1.zip
cd setuptools-33.1.1
python3 setup.py install
wget http://112.124.9.243:8888/wiringpi/friendlyelec-rk3399/wiringpi-2.44.4-py3.6-linux-aarch64.egg
easy_install wiringpi-2.44.4-py3.6-linux-aarch64.egg

最後のところでエラー。easy_installが無いらしい。

pi@NanoPi-NEO4:/var/tmp/setuptools-33.1.1$ easy_install wiringpi-2.44.4-py3.6-linux-aarch64.egg
-bash: easy_install: command not found

見直してみるとpython3 setup.py installの実行時にPermission deniedのエラーがあった。

pi@NanoPi-NEO4:/var/tmp/setuptools-33.1.1$ python3 setup.py install
running install
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

   [Errno 13] Permission denied: '/usr/local/lib/python3.6/dist-packages/test-easy-install-3319.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

   /usr/local/lib/python3.6/dist-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

 https://setuptools.readthedocs.io/en/latest/easy_install.html

Please make the appropriate changes for your system and try again.
