I am having a major issue with the GPIO in virtual env

When I run this code outside my virtual environment, it works. However, when I try to run it inside my virtual env I receive an error. I googled, and ChatGPT for hours. No success. Any thoughts?

Code ran:

from gpiozero import LED
from time import sleep
from signal import signal, SIGTERM, SIGHUP, pause

def safe_exit(signum, frame):
    exit(1)

red = LED(26)

def flashingLights():
    while True:
        red.on()

Error received

I ran into the same issue. Using /usr/bin/python (the system python) will not throw this error, but you probably want to maintain your packages in a virtual env.

My workaround is to run with /usr/bin/python anyway but I also import the packages from my virtual env.

import sys
sys.path.append('/path/to/venv/lib/python3.x/site-packages')

# Now, you can import the package from the venv
import some_package_from_venv

The code you provided did not allow me to repeat the error you received.

Try to do this:

red = LED('GPIO26')

But I'm confused by your requirement file, it's too colorful !?

I would do so:

  1. deactivated venv
  2. deleted the venv folder
  3. reinstalled the dependencies required for this project
  4. created a new requirements file

The hygiene of the virtual environment is very important...

Good luck!
