I'm just gonna post a problem that I've been experiencing for a few days (and having a hard time searching for the answer on the internet) and the solution, so that future questions can refer to this solution.


I'm using Macbook Pro Intel 2020, macOS Monterrey Beta 6


So the problem was when I was running nix-shell in the plutus repository for the first time, and after downloading all the dependencies, the nix-shell stuck at Building library for hnix-#.#.# and [1 of 50] Compiling Nix.Atoms.

What I did before compiling was installing Nix from the official documentation https://nixos.org/download.html

I also did configure the binary cache from https://github.com/input-output-hk/plutus#iohk-binary-cache

Also tried to start with and without https://github.com/input-output-hk/plutus#nix-on-macos

All to no success, still stuck at Building library for hnix-#.#.# and [1 of 50] Compiling Nix.Atoms

  • can I ask how you installed nix-darwin ? I have the same issue as you had (Building library for hnix-#.#.# and [1 of 50] Compiling Nix.Atoms.) I get this error when I try to install it: ~ % nix-build github.com/LnL7/nix-darwin/archive/master.tar.gz -A installer ./result/bin/darwin-installer error: file 'nixpkgs' was not found in the Nix search path (add it using $NIX_PATH or -I), at /nix/store/v1rhxl3ln24zlx8dbmhcrwbwydfmzj6a-master.tar.gz/default.nix:1:13 zsh: no such file or directory: ./result/bin/darwin-installer

So the solution was simply to install nix-darwin


simply follow the instruction on the github page above, and now I can access my nix-shell
