I want to report this error. It has something to do with the latest version 8.4 of Pillow module. If I installed version 7.2, I would not get this error and the example (ssd1306_pillow_text.py) will work just fine with my OLED display.

Below is the complete track message. Again, it only happens when I run the example with version 8.4.

# /ssd1306_oled_display $ /home/pi/Documents/projects/python_examples/new_MyPiHat_v2/Adafruit_CircuitPython_projects/ssd1306_oled_display/venv/bin/python /home/pi/Documents/projects/python_examples/new_MyPiHat_v2/Adafruit_CircuitPython_projects/ssd1306_oled_display/ssd1306_pillow_text.py

I presume you're using pip to install Pillow?

As to why there is a difference, my first suspicion is that we are no longer providing binary wheels for your system - but let's check. Could you show the output of the pip command when you install Pillow 7.2?

As to fixing your problem, I recommend apt-get install libfreetype6-dev

So for 7.2.0 you downloaded https://www.piwheels.org/simple/pillow/Pillow-7.2.0-cp39-cp39-linux_armv7l.whl

And there is also https://www.piwheels.org/simple/pillow/Pillow-8.4.0-cp39-cp39-linux_armv7l.whl, so my initial theory was not correct.

Try building from source instead - pip3 install Pillow --no-binary :all:

apt-get install libjpeg62-turbo-dev and then try pip3 install Pillow --no-binary :all: again.

/home/pi/.pyenv/versions/3.9.7/bin/python -m venv ./venv

I want to comment on this line. I can't use "python3 -m venv ./venv" because pyenv is not able to redirect the 3.9.7 python path (pyenv local 3.9.7) with Raspbian Pi Buster OS. I am still waiting for the pyenv team to solve this issue.

I just want to use a higher version of Python to run Pillow. The default Python3 is 3.7.4 with Raspian Pi Buster OS.

I want to say this so that others may be puzzled why I need to do it this way.

Ok, unless I misunderstand then, this is resolved.
