After running nix-shell in terminal (inside rustlings folder) I get this error, although src/main.rs is already present.

error: couldn't read src/main.rs: No such file or directory (os error 2)

error: could not compile `rustlings` due to previous error

@aritroCoder - Hi, did you solve this? I am getting the same error.

Never mind. Used my own nix shell and ran cargo install --force --path . Seems to work ok now.

I haven't using Nix OS, but recommend you try online run by GitHub Code Space, my Rustlings too at Code Space.

if you're not using flakes you can nix develop --extra-experimental-features nix-command --extra-experimental-features flakes instead of nix-shell Worked for me like a charm. I'm on nix 2.13.6 and NixOS 23.05
