Programs installed via Nix are shadowed by preinstalled MacOS programs

[robbins]

MacOS preinstalls Git in /usr/bin/git (which is really just a command to install Xcode dev tools). Anyways, when I install Git via Nix-Darwin, I'm unable to run it as it always defaults to the preinstalled one.

Checking out $PATH: /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/zfs/bin:/Users/nate/.nix-profile/bin:/run/current-system/sw/bin:/nix/var/nix/profiles/default/bin I see that /usr/bin has precedence over my nix profile.

What's the "Nix way" to move that to the front of $PATH? I guess I could add it to zshrc but I'm not sure if that's the proper solution.

This doesn't happen with programs installed via nix-env, not sure why.

It also happen when I install coreutils via Nix, which is quite irritating that in some shells I have access to Nix installed coreutils (when using Direnv) and sometimes I do not (when in "top-level" shell).

Well, I'm not sure what I did wrong initially but I ended up just reinstalling macOS + Nix + Nix-Darwin and the proper paths are at the start now. Maybe there was some issue in Nix-Darwins ability to edit the /etc/zshrc or other related files, I'm not sure.

But I don't have the issue anymore, although it seems like there might be others with the problem? (I didn't use direnv, though, so maybe it's a different issue). Should I leave this open or close it?

Should be fixed by NixOS/nix#5179

I've just encountered this issue - is there any suggestions on how to fix it? It looks like nixpkgs source code hasn't regressed...
