This is not a Rustlings issue. But still, some people had this issue with Rustlings some days ago. I opned an issue for it on the notify repo: https://github.com/notify-rs/notify/issues/586

For now, the solution is to add --locked. So cargo install --locked cargo-watch

I recommend upgrading notify. You're on a 3 years old release.

Edit: your watchexec stuff is where this comes from, that's 3 years outdated.

Rustlings v6 will be using the latest notify version.
