I am trying to create a virtual environment that can access GPIO pins. In order to do that, I need access to RPi.GPIO in the environment. I am unable to install that into the virtual environment. I managed to make it work by allowing the environment to have access to system packages, but I would like to avoid that.

I installed the latest clean copy of the Raspbian OS, connected to the internet and ran the following commands.

sudo apt-get update
sudo apt-get full-upgrade
python -m venv venv_sandbox
cd venv_sandbox
pip install rpi.gpio

The last command results in a very long error.

Installing collected packages: rpi.gpio

As you can see in the first line of the error message, it said package wheel is not installed so I tried installing that.

pip install wheel
pip install rpi.gpio

The error here seems to be divided into 2 sections

Notes:

  • Running pip freeze does not display wheel as installed after I installed it with pip
  • both python and pip are using version 3
  • everything works (the scripts using GPIO pins) if I set the venv to use system packages

Is there a way to install RPi.GPIO on virtual environments? There are a lot of answers suggesting it can be, but none discuss the issue that I'm having.

If there isn't, is there a way to set the virtual environment to just use this specific system package? I would prefer not to give it access to everything?

  • Pi.GPIO is an enhanced version of RPi.GPIO with additions which has fixes for the python GCC in Bullseye

It looks like the latest release does not support Python 3.9 but the alpha releases do: https://www.piwheels.org/project/RPi.GPIO/

You can install the alpha version with:

pip install rpi-gpio --pre

It seems you are affected by https://sourceforge.net/p/raspberry-gpio-python/tickets/187/, which has been fixed in 0.7.1a2, and is a GCC, not a Python issue. It can be circumvented by doing export CFLAGS=-fcommon first, before installing rpi.gpio. However, the latest stable release 0.7.0 does not fully support RPI4. So you might want to install version 0.7.1a4 anyway.

  • Strictly speaking GCC is not to blame for rejecting everything that is non-standard. It is even helpful when it comes to platform independent development. So it is a problem with raspberry-gpio-python if they use non-standard behaviour or deprecated features. Even if these features have been implemented by intention.
