I figured most package managers (brew, pip, nix, npm, etc.) are not actually one of the few Linux distro package managers. You listed them almost exhaustively after all (excepting pacman).
Right but as I said from the context it was clear he was talking about distro package managers, not language package managers.
Nix requires root (at least by default). Brew I'll give you - I didn't know you can use it on Linux. Do people actually do that enough that it works reliably?
