Are you following the right branch?

[X] My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

Issue description

I have home-manager.useUserPackages = true;, and I haven't changed this.

Inconsistently, I find that I'm missing packages that I have installed in my home-manager programs. Currently, I have neovim enabled and configured, but

$ nvim
The program 'nvim' is currently not installed. It is provided by
...

I can see that it's being installed:

$ ls /etc/profiles/per-user/$USER/bin/nvim
/etc/profiles/per-user/n8henrie/bin/nvim

When I investigate my $PATH, for some reason the /etc/profiles/per-user is missing my username:

$ printf "${PATH//:/'\n'}\n" | grep -e nix -e profile
/Users/n8henrie/.nix-profile/bin
/etc/profiles/per-user//bin
/nix/var/nix/profiles/default/bin

Any ideas what's going on?

Using as a nix-darwin module, flakes. It seems like this problem has happened to me and spontaneously(?) resolved 3 or 4 times now, I can't figure out what's going on.

$ nix eval ~/.dotfiles?submodules=1#darwinConfigurations.NatePro.config.home-manager.users.n8henrie.home.profileDirectory
"/etc/profiles/per-user/n8henrie"

So profileDirectory is being set correctly.

User error.

Part of my bashrc explicitly sets my PATH with a hack[^0]:

NIXPATH=$(
  # shellcheck disable=SC2016
  env -i HOME="${HOME}" sh -c '
      for f in /etc/static/bashrc /nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh; do
        [ -f "${f}" ] && . "${f}"
      done
      echo "${PATH}"
    '
)

PATH=${NIXPATH}:${PATH}

I needed to change it to env -i HOME="${HOME}" USER="${USER}" so that $USER would be available when setting up my environment.
