Helpful notes (Ubuntu/Debian)
On Ubuntu/Debian, the default Vim package is often a minimal build (vim-tiny) that lacks support for plugins like vim-plug.
To fix this, first uninstall the minimal version, then install a full build such as vim-nox or vim-gtk3:

sudo apt remove --purge vim vim-tiny
sudo apt autoremove
sudo apt update && sudo apt install vim-nox

Helpful notes (macOS)
The default Vim that comes preinstalled on macOS is outdated and missing many features required for plugin managers like vim-plug.
It’s recommended to install a modern build via Homebrew:

brew install vim
