Rustc 1.70 clashing with latest clap (4.5.4)

[lgiordani]

Hi! While solving the Redis challenge with Rust I got this error after I pushed to the server. I'm sure I can fix it for now, as I just need to use a previous version of clap, but it might be useful for you to know that some packages now don't support 1.70 any more.

remote: [build] Build failed. Check the logs above for the reason.
remote: [build] If you think this is a CodeCrafters error, please contact us at hello@codecrafters.io.

Should you need to replicate, my current Cargo.toml is

[package]
name = "redis-starter-rust"
version = "0.1.0"
authors = ["Codecrafters <hello@codecrafters.io>"]
edition = "2021"

[dependencies]
anyhow = "1.0.59"                                   # error handling
bytes = "1.3.0"                                     # helps manage buffers
clap = { version = "4.5.4", features = ["derive"] }
thiserror = "1.0.32"                                # error handling
tokio = { version = "1.23.0", features = ["full"] } # async networking

Thanks!

I experimented with different toolchains, however apparently there is a long standing issue in Cargo, and it's not easy to install a previous version of the package clap. This means that with the current setup it is not possible to use the package, I believe.

Any suggestion? Thanks!

Hey @lgiordani! We do support 1.77 now, if you create a new repository the newer version should get picked up.

Thanks @rohitpaulk!
