AttributeError: 'SMBus' object has no attribute 'write_bytes' about adafruit_circuitpython_tsl2591

[berkaysit]

I realized something; if I run the command with sudo like sudo python3 tsl2591_simpletest.py I encounter the error I mentioned above. But it can run without sudo. So, why?

[ladyada]

maybe you have different python libraries installed for root or user 'pi'?

[berkaysit]

I installed the libraries Adafruit_Blinka, Adafruit_CircuitPython_BusDevice, Adafruit_CircuitPython_TSL2591 and I made installation like below for each library:

git clone https://github.com/adafruit/Adafruit_CircuitPython_TSL2591.git
cd Adafruit_CircuitPython_TSL2591
sudo python3 setup.py install

I did not choose any virtual environment. But could you please suggest how to check it? Or do you suggest any other installation method please?

oh dont do that, use pip3
https://learn.adafruit.com/tsl2561/python-circuitpython
follow these instructions, you'll want to uninstall it from the way you did it above

Thank you for your answer. I uninstall my previous installed libraries, and then installed the following;

sudo pip3 install adafruit-blinka
sudo pip3 install Adafruit_CircuitPython_TSL2591

But I still can run python3 example/tsl2591_simpletest.pywithout sudo, but with sudo I encountered the same following error:

sudo python3 tsl2591_simpletest.py

[ladyada]

maybe try 'sudo pip3 install --upgrade adafruit-blinka'
and also 'sudo pip3 install --upgrade Adafruit-GPIO' and 'sudo pip3 install --upgrade Adafruit-PureIO`
