Error installing on Solus

I'm trying to install rivalcfg on Solus with sudo pip3 install rivalcfg, but the installation fails with the following error:

WARNING: You are using pip version 19.2.3, however version 20.2.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I have installed python3, python3-devel and libusb-devel. libudev is apparently included in systemd, so I assume it is installed as well.

According to this Reddit comment it should work out of the box if it is installed with pip3 as i did.

I tried to install hidapi from the solus repository as recomended in https://github.com/flozz/rivalcfg/issues/54#issuecomment-394303959, but the problem persists.

Hello,

It seems you have no C compiler (or it cannot be found?)

Can you try to install system.devel?

sudo eopkg install -c system.devel

(I found this command here)

Thank you! That worked

I will add this in the doc :)
