cargo 构建未使用正确的 rustc 版本

Question

这是一个菜鸟问题，但我刚刚拉了https://github.com/succinctlabs/rsp/并尝试构建它，但失败了

$ cargo build
   Compiling rsp v0.1.0 (/Users/clementwalter/Documents/rsp/bin/host)
error: failed to run custom build command for `rsp v0.1.0 (/Users/clementwalter/Documents/rsp/bin/host)`

Caused by:
  process didn't exit successfully: `/Users/clementwalter/Documents/rsp/target/debug/build/rsp-766fbc07d4535559/build-script-build` (exit status: 101)

  --- stderr
  [sp1]  error: package `reth-trie v1.0.6 (https://github.com/sp1-patches/reth?tag=rsp-20240830#260c7ed2)` cannot be built because it requires rustc 1.80 or newer, while the currently active rustc version is 1.75.0-nightly
  [sp1]  Either upgrade to rustc 1.80 or newer, or use
  [sp1]  cargo update [email protected] --precise ver
  [sp1]  where `ver` is the latest version of `reth-trie` supporting rustc 1.75.0-nightly

虽然我也有

$ rustup show active-toolchain
1.81.0-aarch64-apple-darwin (overridden by '/Users/clementwalter/Documents/rsp/rust-toolchain.toml')

所以我不明白这个1.75版本从何而来，以及为什么选择它

Answer 1

实际上，错误是 rsp 使用了另一个相关项目中定义的自定义工具链。我需要用

sp1up

来更新它。
