I was following through this setup for Doom Emacs but I’m currently stuck with it. I noticed that when I use the fetchGit command, it ends up erroring out saying error: in pure evaluation mode, 'fetchTree' requires a locked input, at /nix/store/8xpb6snxi90adcc2pg6yvnikghdma4bx-source/home-manager/home.nix:74:18
I’m very new to NixOS and I’m not sure what that means exactly. Anyone know how I can modify my config to make it work properly?
I’m using NixOS 23.05 with Home-Manager in standalone and with Flakes
home.nix
