They are using a rustc from August of 2022. If you installed that version, made a new project, and asked for the latest clap, it would not shock me at all if rustc were too old. EDIT: from clap itself: > We will support the last two minor Rust releases (MSRV, currently 1.70.0) So yeah, 1.63.0 is going to be quite old.

Steps to reproduce, once you have cargo and rustc from Debian stable repositories: cargo init && cargo add clap && cargo run. The following happens: error: package `anstream v0.6.4` cannot be built because it requires rustc 1.70.0 or newer, while the currently active rustc version is 1.63.0 Either upgrade to rustc 1.70.0 or newer, or use cargo update -p anstream@0.6.4 --precise ver where `ver` is the latest version of `anstream` supporting rustc 1.63.0

  For what is worth, you can use https://lib.rs https://lib.rs to see the earliest version a crate supports. For Rust 1.63.0, you will have to rely on Clap 4.0.32 from December 2022, instead of anything newer (which only support 1.64.0+): https://lib.rs/crates/clap/versions https://lib.rs/crates/clap/versions For anstream, the situation seems more difficult for you, as it doesn't seem that there's any (non-yanked?) release that supports <1.64.0: https://lib.rs/crates/anstream/versions https://lib.rs/crates/anstream/versions

    Thanks! I was looking for a page like that on docs.rs, crates.io, and possibly on lib.rs as well, but missed it; that is likely to be useful in the future. Actually now I see it on crates.io as well, <https://crates.io/crates/anstream/versions https://crates.io/crates/anstream/versions>. Or maybe I saw it before, and just have not found versions <= 1.63.
