Please let me know how can i fix this error because it always float and so annoying.

Also getting this error with Ubuntu 20 and emacs 27.2. Also getting the same problem when loading emojify. might share a similar root cause?

[pierceglenn12345]

Not sure about the original poster, but once I sent this I realized the problem. I loaded this package through guix. After deleting and re-downloading through melpa, the problem resolves. I'll leave open in case there are other issues.

Having the same issue when getting symon via straight.el.

Per @pierceglenn12345, when installing with MELPA I have no issues.

EDIT: Maybe there is a regression in git master?

For more info, I am running Void Linux and have expected cat /proc/meminfo behavior.
