Any way to prevent using `sudo`? about brightness HOT 5 OPEN

You mean with the CLI? You should never install global packages with sudo to begin with. https://github.com/sindresorhus/guides/blob/master/npm-global-without-sudo.md

After that, you shouldn't be forced to use sudo when using the cli.

I think sudo is required to be able to run it on Linux regardless. There's an open PR which addresses this #11.

Did anybody meet with the problem when installing the packages?

Sudo is not required on Linux if you add xorg-xbacklight as a dependency. See an example here https://github.com/i3bar/core/blob/db7cc783283020a45dac3e805fa6c6eb8f2fc6ee/example/utils.js#L87
