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](https://raspberrypi.stackexchange.com/a/117593/8697) is an enhanced version of RPi.GPIO with additions which has fixes for the python GCC in Bullseye – Milliways Jan 08 '22 at 23:29

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. – Tobias Schlemmer Jan 09 '22 at 17:20
