importlib.metadata.PackageNotFoundError: Command runtime error

Describe the bug I’ve just installed Arch and setup the Nvidia driver. Everything seems fine on my old system, but I had this error today.

Steps to reproduce Run optimus-manager an error occurred:

Traceback (most recent call last):
File "/usr/bin/optimus-manager", line 9, in <module>
for entry_point in distribution('optimus-manager==1.3').entry_points:
File "/usr/lib/python3.8/importlib/metadata.py", line 504, in distribution
return Distribution.from_name(distribution_name)
File "/usr/lib/python3.8/importlib/metadata.py", line 177, in from_name
raise PackageNotFoundError(name)
importlib.metadata.PackageNotFoundError: optimus-manager==1.3

System info

• ArchLinux (dkms kernel)
• KDE
• SDDM
• Occurred in both versions (optimus-manager and optimus-manager-git)
• Default settings

Logs Unfortunately, I can’t run optimus-manager command. So, here the log that I can provides: /var/log/optimus-manager/switch/

EDIT: I’m using optimus-manager-qt to try switching from Intel to NVIDIA but had no luck. Additional information for my packages:

## NVIDIA
local/nvidia-dkms 440.82-2
local/nvidia-settings 440.82-1
local/nvidia-utils 440.82-2

## OpenGL
local/lib32-mesa 20.1.1-2
local/mesa 20.1.1-1

For python packages and its pip list: Hastebin

Kernel: 5.7.2-zen1-1-zen

I had the same problem. Fixed it in this order:

• uninstall optimus-manager-git and optimus-manager-qt
• delete the pamac cache
• install optimus-manager (not the optimus-manager-git package) and optimus-manager-qt

DE-Gnome/Kernel 5.15 Manjaro

Does python -c "import optimus_manager" return any error ?

No, it does not show anything.

And thanks to @Jerrs for mentioning the workaround for this problem!

EDIT: These (console_script) files also using distribution('optimus-manager==1.3') instead of distribution('optimus-manager'):
