wiringpi and easy_install on NanoPi M4

[Jeffer]

I'm trying to install wiringpi by following the instruction given here https://github.com/Pavelectric/WiringPi_M4.

Most of the steps that I followed worked fine but when I do the very last command below,

$ sudo easy_install wiringpi-2.44.4-py3.6-linux-aarch64.egg

I get a following error,

ImportError: cannot import name 'ContextualZipFile'

I googled how to deal with this kind of error, and some people tell that 'ContextualZipFile'  in archive_util.py doesn't have to be installed so I just need to comment that out.

Although, I couldn't find  '/usr/local/lib/python3.6/dist-packages/setuptools-33.1.1-py3.6.egg/setuptools/archive_util.py', 

I did that comment out solution to the all files below, which I got by doing find-command-research

Now I don't know what to do here... It is very nice if anyone can help me get out of this darkness...

 

Thank you,

Good day. First try for Python 2:

$ sudo easy_install-2.7 wiringpi-2.44.4-py2.7-linux-aarch64.egg

I understand that you need the 3rd Python, but still ...

Thank you for replying to my question.

After I tried with different .img file, which is nightly I think, everything worked well.

I successfully installed wiringpi both in Python2 and Python3.

 

But a problem now is that I get "Segmentation fault" errors when I try to use call back function with 

wiringpi.wiringPiISR(PIN_TO_SENSE, wiringpi.GPIO.INT_EDGE_BOTH, gpio_callback)

in some codes such as shown here https://github.com/WiringPi/WiringPi-Python/blob/master/examples/callback.py.

 

as soon as I command 

wiringpi.wiringPiISR(PIN_TO_SENSE, wiringpi.GPIO.INT_EDGE_BOTH, gpio_callback)

the gpio_callback function which I defined execute some times (typically ~10 times), 

that segmentation fault error occurs.

 

I have tested it with python2 and python3 as well.

Do you have any idea why this happens or maybe how to deal with this?

 

Thank you,
