Flask error: [ModuleNotFoundError: No module named 'RPi']

I am making a simple Flask app on Raspberry pi, but I cannot include import RPi.GPIO as GPIO in python code. This is the output error:

 * Serving Flask app "rgbw.py"
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
Usage: flask run [OPTIONS]

Error: While importing "rgbw", an ImportError was raised:

Traceback (most recent call last):
  File "/var/www/html/rgbw/venv/lib/python3.7/site-packages/flask/cli.py", line 240, in locate_app
    __import__(module_name)
  File "/var/www/html/rgbw/rgbw.py", line 5, in <module>
    import RPi.GPIO as GPIO
ModuleNotFoundError: No module named 'RPi'

I have installed GPIO inside the virtual environment, so I don't know why it doesn't want to work.

Thanks for help!

Interesting... I tried pip install RPi.GPIO, and it didn't solve my problem (working ony when running the python program from Geany, but not from the terminal).

sudo apt-get -y install python3-rpi.gpio solved the issue, making it possible to run my program from the terminal.

Have you got RPi.GPIO installed? (You can check by running pip freeze in the virtual environment.) If not you can install it with: pip install RPi.GPIO

import RPi.GPIO as GPIO is trying to import the function GPIO from the library RPi.GPIO which is not the same library as GPIO.

I hope this solves your problem, if not please add a copy of your code and pip freeze to your question.
