I was not able to determine why this package is not available on pypi (#6 does not explain), and I don't have any compatible hardware to test. If you manually copy the adafruit_ssd1327.py file into your project is it working for you? Normally we disable uploading to pypi when we know that the code is not compatible with Blinka and can only work with CircuitPython.

I think this was from before Blink_Displayio existed so it would have not been possible at the time. It may work fine now. I don't have hardware to check either though.

I've only used with a CircuitPython board before, here is how I tried it on Raspberry Pi, it fails:

pip3 install RPI.GPIO
pip3 install adafruit-blinka
pip3 install adafruit-blinka-displayio
pip3 install adafruit-circuitpython-display-text
git clone https://github.com/adafruit/Adafruit_CircuitPython_SSD1327.git
cp Adafruit_CircuitPython_SSD1327/examples/ssd1327_simpletest.py .
cp Adafruit_CircuitPython_SSD1327/adafruit_ssd1327.py .
python3 ssd1327_simpletest.py

Output is:

Ah, it appears that Adafruit_Blinka_Displayio does not yet support i2c displays at all. https://github.com/adafruit/Adafruit_Blinka_Displayio/issues/2 -- once issue 2 is addressed in that repo, it would then be useful to upload this package to pypi. At present it appears that only FourWire (SPI) displays are supported.
