【问题描述】:
我使用的是 macOS 10.13.5,正在学习 Rust 编程,我使用 Nix 来控制我的开发环境。
某些操作(例如包含jsonwebtoken 库或安装cargo-watch 模块)会导致构建需要似乎未安装的macOS 框架。我收到此错误消息:
= note: ld: framework not found CoreServices
clang-5.0: error: linker command failed with exit code 1 (use -v to see invocation)
error: aborting due to previous error
error: failed to compile `cargo-watch v6.0.0`, intermediate artifacts can be found at `/var/folders/13/84dj8yr54_1c_pn0s8n7444h0000gn/T/cargo-install.lYPZaEduUBdu`
Caused by:
Could not compile `cargo-watch`.
这是失败的 clang 命令的缩写版本:
error: linking with `/nix/store/9j864incgjx7kqggbpisdi3nmssy4qm5-clang-wrapper-5.0.2/bin/cc` failed: exit code: 1

= note: "/nix/store/9j864incgjx7kqggbpisdi3nmssy4qm5-clang-wrapper-5.0.2/bin/cc" "-m64" "-L" ...

我发现唯一尝试的是将框架添加到我的 PATH 中,但要么这个答案是错误的,要么 PATH 环境变量无法通过货物一直到我正在构建的地方有问题。
- Clang(LLVM) compile with frameworks
锈:1.24.0
- 货物:0.25.0
- jsonwebtoken:0.4.0
- cargo-watch:默认版本来自
cargo install cargo-watch
我如何告诉 clang 在哪里寻找框架?它是否涉及对我的工作环境的更改,或者我是否需要考虑更改我要安装的 crate 的构建过程?

我发现了clang -Xlinker -v 命令,输出很有趣:

这似乎指向我的 Nix shell 中缺少的东西,而不是操作系统甚至 clang 本身。
