# Solana 实现链上数据存储器 从零开始搭建，即便对照讲解修改配置文件 Cargo.toml 编译时依然报错，且各种尝试都无法解决 ```plaintext # cargo build-sbf error: failed to download `constant_time_eq v0.4.2` Caused by: unable to get packages from source Caused by: failed to download replaced source registry `crates-io` Caused by: failed to parse manifest at `/root/.cargo/registry/src/rsproxy.cn-0dccff568467c15b/constant_time_eq-0.4.2/Cargo.toml` Caused by: feature `edition2024` is required The package requires the Cargo feature called `edition2024`, but that feature is not stabilized in this version of Cargo (1.84.0 (12fe57a9d 2025-04-07)). Consider trying a more recent nightly release.
