Platform

Additional information

I'm using Project IDX and whatever I'm trying to install, I was given option to explore NIX first (tbh this is my first time hearing this word). I tried to install the python packages using NIX but, got error "NIX NOT FOUND," and then afterwards I went to the site of NIX to install it and rest can be understand in the Ouput

Output

Output ```log build-nanogpt-3262913:~/build-nanogpt{master}$ curl -L https://nixos.org/nix/install | sh -s -- --daemon % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 100 4052 100 4052 0 0 7506 0 --:--:-- --:--:-- --:--:-- 7506 downloading Nix 2.22.1 binary tarball for x86_64-linux from 'https://releases.nixos.org/nix/nix-2.22.1/nix-2.22.1-x86_64-linux.tar.xz' to '/tmp/nix-binary-tarball-unpack.ZC31gC5j1o'... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 21.9M 100 21.9M 0 0 92.8M 0 --:--:-- --:--:-- --:--:-- 92.8M Note: a multi-user installation is possible. See https://nixos.org/manual/nix/stable/installation/installing-binary.html#multi-user-installation Switching to the Multi-user Installer Welcome to the Multi-User Nix Installation This installation tool will set up your computer with the Nix package manager. This will happen in a few stages: 1. Make sure your computer doesn't already have Nix. If it does, I will show you instructions on how to clean up your old install. 2. Show you what I am going to install and where. Then I will ask if you are ready to continue. 3. Create the system users (uids [30001..30032]) and groups (gid 30000) that the Nix daemon uses to run builds. To create system users in a different range, exit and run this tool again with NIX_FIRST_BUILD_UID set. 4. Perform the basic installation of the Nix files daemon. 5. Configure your shell to import special Nix Profile files, so you can use Nix. 6. Start the Nix daemon. Would you like to see a more detailed list of what I will do? No TTY, assuming you would say yes :) I will: - make sure your computer doesn't already have Nix files (if it does, I will tell you how to clean them up.) - create local users (see the list above for the users I'll make) - create a local group (nixbld) - install Nix in to /nix - create a configuration file in /etc/nix - set up the "default profile" by creating some Nix-related files in /root - back up /etc/bashrc to /etc/bashrc.backup-before-nix - update /etc/bashrc to include some Nix configuration - back up /etc/zshrc to /etc/zshrc.backup-before-nix - update /etc/zshrc to include some Nix configuration - load and start a service (at /etc/systemd/system/nix-daemon.service and /etc/systemd/system/nix-daemon.socket) for nix-daemon Ready to continue? No TTY, assuming you would say yes :) ---- let's talk about sudo ----------------------------------------------------- This script is going to call sudo a lot. Normally, it would show you exactly what commands it is running and why. However, the script is run in a headless fashion, like this: $ curl -L https://nixos.org/nix/install | sh or maybe in a CI pipeline. Because of that, I'm going to skip the verbose output in the interest of brevity. If you would like to see the output, try like this: $ curl -L -o install-nix https://nixos.org/nix/install $ sh ./install-nix ~~> Checking for artifacts of previous installs Before I try to install, I'll check for signs Nix already is or has been installed on this system. /tmp/nix-binary-tarball-unpack.ZC31gC5j1o/unpack/nix-2.22.1-x86_64-linux/install-systemd-multi-user.sh: line 60: systemctl: command not found /tmp/nix-binary-tarball-unpack.ZC31gC5j1o/unpack/nix-2.22.1-x86_64-linux/install-systemd-multi-user.sh: line 61: systemctl: command not found ---- warning! ------------------------------------------------------------------ Nix already appears to be installed.

I believe IDX offers its own Nix integration, based on https://idx.dev/blog/article/nix-on-idx. The article links this technical documentation as well. I don't see any mention of using the nix command, so maybe what's going on is that IDX uses Nix to build a customizable but static environment that does not include Nix itself. Nix already appears to be installed. in your installer log appears to contradict this, but that may just indicate the presence of aforementioned pre-built Nix store, or perhaps a previous failed installer run.

The lack of sudo indicates that you were not given sufficient control of the IDX environment, which is probably by design. Considering that Google manages your Nix store, could you ask them whether this is a use case they support?

Just to give more precision on the idx setup (as far as I know): it is indeed using Nix to install everything, and Nix should be available in the environment, but you're not supposed to install it yourself. Everything happens by modifying the .idx/dev.nix file mentioned here

Not sure what causes the "NIX NOT FOUND," message. It's probably related to the specific setup of IDX

Hi @DeepakKumarKhatri ,

I am on the IDX team and wanted to provide an answer here.

As already pointed out, you don't need to install nix on idx, it's already installed and available there, you are free to use the nix cli there and if your need a certain version that is different from the one we have installed by default, you can add it to your .idx/dev.nix file, e.g. pkgs.nixVersions.nix_2_XX however note that all builds will be handled by the daemon that as of today is at version 2.23.

That said, we don't require that developers build their code with nix, what we provide is a way for you to configure your developer toolchain/environment with nix, after that you're free to use the "native" build tools of your target platform, e.g. npm, gradle, maven, cargo, poetry, etc.

As for sudo, as @roberth correctly inferred, we don't currently provide sudo access and I would argue that it's for the most part useless inside IDX, i.e. you won't have write access to the filesystem outside of /home /tmp even with sudo. We have some ideas on relaxing these restrictions but it has not been prioritized as we've not seen much demand for it so far.

However one of the biggest hurdles with sudo is that it's ingrained in many developers' muscle memory so they naturally use sudo when it's actually not required, one such example.

If you have further questions feel free to ask them at https://community.idx.dev/
