英文:
Rust multiple crates fail to compile due to permission denied
问题
当我构建一个带有依赖项的项目时，构建脚本会因权限被拒绝而失败。这不会发生在每个 crate 上。以下是尝试构建一个 WGPU 项目时的输出。
错误: 无法运行 `objc_exception v0.1.2` 的自定义构建命令
造成原因:
进程没有成功退出: `/Users/64001830/wgpu-test/target/debug/build/objc_exception-f7c40ee498546635/build-script-build` (退出状态: 1)

我已经尝试过重启、创建新项目、卸载并重新安装 Rust，但仍然遇到相同的问题。

Ive tried restarting, new projects, uninstalling and reinstalling rust.

From the error (specifically this line: CC = Some("/usr/bin/")) you can see that the C compiler environment variable (CC) is set to /usr/bin/ which is not a valid C compiler.
You can either clear the environment variable or set it to something useful like /usr/bin/cc, /usr/bin/gcc or the path to your C compiler of choice.
