New nix installation fails on macOS

brandondrew commented 5 years ago

I freshly installed Nix on macOS Mojave 10.14.3 (18D42) and had the same experience in both iTerm and Terminal:

💻  . /Users/brandon/.nix-profile/etc/profile.d/nix.sh
/Users/brandon/.nix-profile/etc/profile.d/nix.sh:stat:14: %u: no such file or directory
Nix: WARNING: bad ownership on /nix/var/nix/profiles/per-user/brandon, should be 501
/Users/brandon/.nix-profile/etc/profile.d/nix.sh:stat:39: %u: no such file or directory
Nix: WARNING: bad ownership on /nix/var/nix/gcroots/per-user/brandon, should be 501

Regarding the warnings, I verified that I'm user 501:

💻  id -u                                                                                               61486  02-19 20:04 EST  ~  Haddock
501

The portions of the file with the errors are:

14     if [ "$(stat --printf '%u' "$NIX_USER_PROFILE_DIR")" != "$(id -u)" ]; then
15         echo "Nix: WARNING: bad ownership on "$NIX_USER_PROFILE_DIR", should be $(id -u)" >&2
16     fi

and

39         if [ "$(stat --printf '%u' "$__user_gcroots")" != "$(id -u)" ]; then
40             echo "Nix: WARNING: bad ownership on $__user_gcroots, should be $(id -u)" >&2
41         fi

The verification that the installation failed was that I could not install anything:

💻  nix-env -i elvish                                                                                   61490  02-19 20:07 EST  ~  Haddock
zsh: command not found: nix-env

P.S. I looked through several macOS issues with related titles, but this did not appear to be like the others I saw.

It looks like you are getting the stat from /usr/bin/ and not the stat from coreutils. Can you make sure that this line is setting PATH correctly: https://github.com/NixOS/nix/blob/master/scripts/nix-profile.sh.in#L3

You should be able to run this successfully:

PATH=@coreutils@ stat --printf '%u' .

where @coreutils@ is the actual path to coreutils in nix.sh.

I think this may be obsolete.

I don't see any references to stat --printf, NIX_USER_PROFILE_DIR or __user_gcroots in the Nix repo.

I marked this as stale due to inactivity. → More info
