我在macOS 10.13.5上学习编程，我使用Nix控制我的开发环境.

有些操作，例如包括jsonwebtoken库或安装cargo-watch模块，会导致生成需要macOS框架的版本，但该版本似乎未安装.我收到以下错误消息:

  = 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

我发现唯一可以try 的是向PATH中添加框架，但要么这个答案是错误的，要么PATH环境变量无法通过Cargo 到达我正在进行的构建的地方.

• Clang(LLVM) compile with frameworks

• 一百

• rust 蚀:1.24.0

• Cargo :0.25.0
• jsonwebtoken:0.4.0
• cargo watch:默认版本为cargo install cargo-watch

我如何告诉clang在哪里寻找框架？这是否涉及改变我的工作环境，或者我是否需要考虑改变我想要安装的 crate 的构建过程？

我发现了clang -Xlinker -v命令，输出非常有趣:

这似乎指向了我的Nix shell中缺少的东西，而不是操作系统，甚至是clang本身.
