Sounds like you need to update your rust version. rust-lang/rust#91611

@doroved I had the same error due to having two rust versions (cargo and homebrew) - in my case what solved was brew uninstall rust and then rustup update. Then I was able to see the proper rustc referenced:

> which rustc
/Users/hugo/.cargo/bin/rustc
