smbus install issues

[MartenKL]

When running; "sudo python3 setup.py install" I encounter an error; "ModuleNotFoundError: No module named 'smbus'"

I have tried installing smbus and smbus2 with pip, pip3 pip3.6 no combination worked. running; "sudo apt-get install python3-smbus" works and installs smbus but only for Python 3.5.3, not Python 3.6.5 Is there a simple way to copy the library from 3.5.3 to 3.6.5?

The raspbian python3-smbus installs in /usr/lib/python3/dist-packages

pi@raspberrypi:~ $ dpkg-query -L python3-smbus
/.

/usr/lib
/usr/lib/python3

In your Python 3.6 do:

import sys
print(sys.path)

Check if /usr/lib/python3/dist-packages is included in the path. If so import smbus should work in python 3.6 as far as I know.

It is not in my path but when I add it I get the same result: pi@ZeroPaper:~ $ python3 Python 3.6.5 (default, May 3 2018, 21:34:56) [GCC 6.3.0 20170516] on linux Type "help", "copyright", "credits" or "license" for more information.

smbus2 on PyPi is supported for python 3.6. You will need to change all import smbus statements to import smbus2.

Alternatively you can look at my py-smbusf in https://github.com/PiSupply/PaPiRus/tree/master/RTC-Hat-Examples/py-smbusf In setup.py change the module name from smbusf to smbus, then you do not have to change the scripts.
