'NeoPixel' object has no attribute 'buf'

See original GitHub issue

I just set up a new Raspberry 3. I did pip3 install adafruit-circuitpython-neopixel This installed version 4.1.0

No when I start any program this happens:

File "/usr/local/lib/python3.7/dist-packages/adafruit_pypixelbuf.py", line 260, in __setitem__
    self.show()
  File "/usr/local/lib/python3.7/dist-packages/neopixel.py", line 151, in show
    neopixel_write(self.pin, self.buf)
AttributeError: 'NeoPixel' object has no attribute 'buf'

When I do this: pip3 install adafruit-circuitpython-neopixel==4.0.0 everything works again.

I hope this helps. Sincerely HWende

GPIO access is permitted without root access, mmio is not. you have to run any and all neopixel code on a Pi as root
