I'm trying to develop a simple feature in a new Rust project and every time that I add the serde crate (https://crates.io/crates/serde) my build stops working. Not sure why. At the bottom of the command there is a "No such file or directory (os error 2)" message. But that is a clean install using rustup. Can that be related?
That's the output:
$ cargo build -vv
Dirty proc-macro2 v1.0.69: stale, unknown reason

I created a new project from scratch: new folder, cargo init, cargo add serde and then cargo build. In this completely isolated environment I expected that it'd build without any errors.
