i am new to nix. in my shell.nix file when i refer to pkgs.go it downloads Go 1.20.8.

How do i tell it to download Go 1.21?

Use pkgs.go_1_21.

BTW, there is a tracking issue for moving to Go 1.21 by default: https://github.com/NixOS/nixpkgs/issues/255907.

@pdeva if your problem was solved, could you please share your shell.nix? I’m having the following issue:

            5|   nativeBuildInputs = with pkgs; [
            6|     pkgs.go_1_21
             |     ^
            7|   ];
       Did you mean one of go_1_20, go_1_18 or go_1_19?

Probably it’s by how I am defining it:

   1   │ let
   2   │   pkgs = import <nixpkgs> {};
   3   │ in
   4   │ pkgs.mkShell {
   5   │   nativeBuildInputs = with pkgs; [
   6 ~ │     pkgs.go_1_21
   7   │   ];
   8   │ }

i believe now the standard go nix pkg has been updated to 1.21
