nix-shell not accessible although installation completed successfully about nix HOT 7 CLOSED

NIX_PROFILES actually is space-delimited, so that should be fine. (And ~/.nix-profile will only get created as-needed--that shouldn't be a problem, either.)

 ~  nix-shell
error: path '/Users/philipp/default.nix' does not exist

This indicates that nix is present on your PATH, now--so I think you're sorted. Either something you've tried changing, or perhaps restarting your shell, has fixed it. You should be able to confirm with nix-shell -p hello or somesuch.

from nix.

Nix not being on PATH generally points to your shell init files either hard-setting a PATH that doesn't include Nix after Nix's shell hook ran (often from one of the user-specific init files in ~/), or perhaps having an early return condition in the relevant init file that is keeping the shell hook from running at all.

If env | grep NIX shows a few variables, that's a good sign the shell hook is at least running and you can focus on looking for what might be overwriting PATH.

@abathur thanks for your support, that's really odd I've checked all the possible dotfiles in my homedir such as

# ~ ls -a | grep ".zsh*"
.oh-my-zsh
.shell.pre-oh-my-zsh
.zsh_history
.zsh_sessions
.zshenv
.zshrc

Included a print checking whether zshrc is picking up nix-daemon.sh (it does) and even sourced the file manually after starting a shell - but with no effect.

And shell hook seems to be running indeed:

env | grep nix
NIX_PROFILES=/nix/var/nix/profiles/default /Users/philipp/.nix-profile
XDG_DATA_DIRS=/usr/local/share:/usr/share:/Users/philipp/.nix-profile/share:/nix/var/nix/profiles/default/share
NIX_SSL_CERT_FILE=/nix/var/nix/profiles/default/etc/ssl/certs/ca-bundle.crt

# echo $PATH
/Users/philipp/.opam/default/bin:/usr/local/share:/usr/share:/Users/philipp/.nix-profile/share:/nix/var/nix/profiles/default/share:/nix/var/nix/profiles/default /Users/philipp/.nix-profile

Also tried this workaround

from nix.

# echo $PATH
/Users/philipp/.opam/default/bin:/usr/local/share:/usr/share:/Users/philipp/.nix-profile/share:/nix/var/nix/profiles/default/share:/nix/var/nix/profiles/default /Users/philipp/.nix-profile

The last separator in this PATH is a space instead of a semicolon; I guess it might be breaking the PATH search for both of the last two entries.

If PATH="/Users/philipp/.opam/default/bin:/usr/local/share:/usr/share:/Users/philipp/.nix-profile/share:/nix/var/nix/profiles/default/share:/nix/var/nix/profiles/default:/Users/philipp/.nix-profile" type nix-shell finds the executable, then you'll need to figure out where/how the space is slipping in.

@abathur sorry, this has been an c&p error, actually there's no whitespace - but see below, there's no Users/<myuser>/.nix-profile directory existent.

env | grep nix
PATH=/Users/philipp/.opam/default/bin:/Users/philipp/.nix-profile/bin:/nix/var/nix/profiles/default/bin:/Users/philipp/go/bin/tparse:/opt/homebrew/opt/llvm/bin:/opt/homebrew/opt/llvm/bin:/opt/homebrew/bin/python3:/opt/homebrew/Cellar/zplug/2.4.2/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/philipp/.cargo/bin

 ~  nix-shell
error: path '/Users/philipp/default.nix' does not exist

from nix.

in nix-daemon.sh its:

export NIX_PROFILES="/nix/var/nix/profiles/default $NIX_LINK"

aint it supposed to be:

export NIX_PROFILES="/nix/var/nix/profiles/default:$NIX_LINK"

from nix.

thanks a lot for your support, I ended up by just copying setting up/exporting the PATH from nix-daemon.sh directly into my zshrc like this:

NIX_LINK=$HOME/.nix-profile
export NIX_PROFILES="/nix/var/nix/profiles/default:$NIX_LINK"
export XDG_DATA_DIRS="/usr/local/share:/usr/share:$NIX_LINK/share:/nix/var/nix/profiles/default/share"
export PATH="$NIX_LINK/bin:/nix/var/nix/profiles/default/bin:$PATH"

Still haven't been able to figure out why my PATH haven't been set up correctly but at least it's working now
