【问题描述】：
我正在使用以下 rust 存储库：
https://github.com/SmartCodeBlockchainDev/Nelson-NFT-stacking
当我尝试进行锚点构建时，出现以下错误：
Failed to obtain package metadata: `cargo metadata` exited with an error: Updating crates.io index
error: failed to select a version for the requirement `anchor-lang = "^0.20.1"`
candidate versions found which didn't match: 0.24.2
location searched: crates.io index
required by package `nft-staking v0.1.0 (/staking/programs/staking)`
当我将 cargo.toml 文件更新到这些版本（anchor-lang 和 anchor-spl 0.24.2）时，lib.rs 中出现了几个错误：

Some errors have detailed explanations: E0277, E0432, E0599.
