pkg_resources.DistributionNotFound: The 'msi-perkeyrgb==2.1' distribution was not found and is required by the application

[Linux-Fan]

My system is a 64-bit Arch Linux

Linux titanlinux 5.3.11-arch1-1 #1 SMP PREEMPT Tue, 12 Nov 2019 22:19:48 +0000 x86_64 GNU/Linux

I installed msi-perkeyrgb from AUR but for some time I cannot run it, although it was working previously. I have all the necessary requirements installed.

$ sudo msi-perkeyrgb -c /home/zbyszek/Desktop/Arch\ Linux/Konfiguracja\ Arch\ Linux/Po\ instalacji/MSIKeyboardconfig

Yeah the Python 3.8 update on Arch broke stuff. The solution is to rebuild the package from scratch. If you use a AUR helper like yay, make sure to do a cleanbuild.

I'll just bump the $pkgrel so that AUR helpers pick up the update and trigger a rebuild.

It works again, thanks!
