Of anyone has experience setting up piglow please help me out, I literally just want it on when I boot, or just on period, I think I’ve followed the tutorials correctly, but I just can’t get past the test part I keep getting

pi@retropie ~ $ cd piglow
pi@retropie ~/piglow $ sudo python test.py
Traceback (most recent call last):
File “test.py”, line 7, in <module>
from piglow import PiGlow
File “/home/pi/piglow/piglow.py”, line 16, in <module>
import RPi.GPIO as rpi
ImportError: No module named RPi.GPIO
pi@retropie ~/piglow $

Thanks in advance

Yea I did but now that I think of it l, I didn’t add “sudo” in front of it, I just did pip install RPi.GPIO, I’m not sure if it makes a difference, but when I did that I didn’t get any error messages, maybe when I get home today I’ll try that part again, what about

sudo pip install -U RPi.GPIO

I saw that somewhere

I tested the above command on retropie and it worked for me (after doing it i could import the library fine)

Hey buzz that was it

sudo pip install -U RPi.GPIO

Was all I needed, after that I was able to run the python scripts, all I have to do is figure out how to get it running on boot, what I’m afraid of is that when I run a piglow script it’s clouds the terminal with feedback from the piglow, I hope it doesn’t always do that, I’m not sure how to stop it other than rebooting

I’ve got the script working perfectly on boot, and the lights go out when I shutdown as well, I’m happy with this purchase, I’ll be posting pictures of my custom made LegoPi console soon
