i try to change the rustc version to
rustup default nightly-2024-05-01-x86_64-unknown-linux-gnu
And show the version of rustc 1.84.0-nightly (9322d183f 2024-10-14)
, but all of them are useless!!

Can you update to a Rust version newer than 1.60? This is the minimum supported version: https://github.com/rust-lang/log?tab=readme-ov-file#minimum-supported-rustc.

yes, i solved it by uninstall all other version
$ rustup toolchain list && rustup uninstall XXXX-linux-gnu*;
$ rustc --version
only keep the latest rustc 1.84.0-nightly (9322d183f 2024-10-14);

i find the problem was caused by Cargo.toml dependencies , there are some other crate which is too old and them have dependencies on oler log crate.

so i must keep the dependencies and version of rustc in latest sates.\thanks for your suggestion,.
