Fresh install isn't working about led-control

[jackw01]

I recently had an issue doing a fresh install of this and changed ledcontrol/rpi_ws281x/__init__.py to fix it, but I'm not sure why the fix was necessary or why it even fixed anything.

Can you try replacing the contents of /home/pi/led-control/ledcontrol/rpi_ws281x/__init__.py with this?

# led-control WS2812B LED Controller Server

from .rpi_ws281x import PixelStrip, Color
from .lib.rpi_ws281x import (
    blackbody_to_rgb,
    blackbody_correction_rgb,
    wave_pulse,
    wave_triangle,      
    wave_sine,
    wave_cubic,
    plasma_sines,       
    plasma_sines_octave,
    perlin_noise_3d,    
)

__version__ = '4.2.2'

If this doesn't work, the issue is likely something with the build process for the C extension module.

I get the following if I replace the contents of init.py:

Any idea ?

Great project mate ..... I'm having the exact same issue.

@WhiteyFord cannot reproduce, what version of Raspberry Pi OS are you running and are you following the exact setup instructions in README.md?

When I run it, the first line printed is /home/pi/led-control/_rpi_ws281x.cpython-37m-arm-linux-gnueabihf.so instead of /usr/local/lib/python3.7/dist-packages/_rpi_ws281x.cpython-37m-arm-linux-gnueabihf.so which indicates that something is different about how it was installed. The _rpi_ws281x binary does not end up in /usr/local/lib/python3.7/dist-packages on my test devices.

Got a chance to test this with a fresh install of the latest version of Raspberry Pi OS. It did not have any issues installing when I followed the directions in README.md.
