Cannot install nix package manager without sudo privileges (lemmy.ml)

First of all, I'm completely new to Nix and I have no idea what I'm doing. I would like to use it initially as a more general purpose replacement of conda environments for my AI-development workflow. To begin with, I'd like to install nix package manager at my work server where I don't have root access. I tried

sh <(curl -L https://nixos.org/nix/install) --no-daemon

however it tries to create /nix which I cannot do without sudo. I searched everywhere, but I don't seem to find a way to circumvent this.

Thanks!

Thanks, this explains it. I'm trying to set up nix-portable now, but it's quite confusing. I downloaded nix-portable binary which is a self-extracting archive that silently unpacked a bunch of files to ~/.nix-portable:

$ ls ~/.nix-portable/bin/
bwrap  proot  zstd

It seems I was meant to run it like so ./nix-portable nix-shell but this does nothing. On my local machine running OpenSUSE Tumbleweed it exists immediately, whereas on my work HPC server it gets stuck.

That's all right, thanks! It seems that it does do something indeed, I had to run with debug information and it was simply taking a long time to configure itself

NP_DEBUG=2 ./nix-portable nix-shell -p hello

The only issue is I downloaded a binary package which is dated early 2022 and it uses nix 2.5.1. I need to figure out how to force it to use the latest version of nix.

You may wanna have a look at nix-portable if you don't have root access.

Above command will perform a single-user installation of Nix, meaning that /nix is owned by the invoking user. You should run this under your usual user account, not as root. The script will invoke sudo to create /nix if it doesn’t already exist.

Thanks! I do run it indeed as a user. I don't have a sudo access on this server so I would like to do a completely portable installation. I downloaded a portable binary for nix https://releases.nixos.org/?prefix=nix/nix-2.16.1/ and unpacked it on a file system, however when running nix it thinks that nix store is at /nix/store:

$ /work/apps/nix/store/jdijjdjl6gjh07s4mwgb6bvm501hmjvh-nix-2.16.1/bin/nix
-bash: /work/apps/nix/store/jdijjdjl6gjh07s4mwgb6bvm501hmjvh-nix-2.16.1/bin/nix: /nix/store/4nlgxhb09sdr51nc9hdm8az5b08vzkgx-glibc-2.35-163/lib/ld-linux-x86-64.so.2: bad ELF interpreter: No such file or directory

So far I wasn't able to configure a different location for nix store: I created ~/.config/nix/nix.conf and put this line inside nix.storeDir = /work/apps/nix/store but it couldn't pick up the custom store location.
