Neofetch doesn't show # of installed packages when running Nix on macOS

shaunsingh commented 3 years ago

Description

After installing nix as well as neofetch through nix, neofetch will not display the number of packages installed on the system

Only enough, if you install both homebrew and nix, then install neofetch through homebrew, then it does display the number of packages properly (for both nix and homebrew). If you install both homebrew and nix, then install neofetch through nix, it incorrectly shows the number of packages (shows that it only has one package though brew, no mention of nix)

[x] Does this issue still occur in the master branch? (Required if issue) Happens after installing through running sudo make PREFIX=/usr/local install on the cloned repo, as well as installing through nix-env -iA neofetch

Neofetch version

Neofetch 7.1.0

Not a neofetch bug. Brew doesn't seem to be in your PATH according to the verbose log as it is never found. The Nix commands error out and therefore no packages are shown.

The commands for Nix on macOS could be different I suppose?

shaunsingh commented 3 years ago

I'm using a single-user installation if it makes any difference.

I'm not familiar with how the Nix utilities work (on Linux or MacOS) so we must wait for someone with the expertise.

This command should work on both NixOS, Linux running the Nix package manager, and macOS running the Nix package manager for querying the number of packages installed on a system: $ nix-env --query | wc -l
