    这是一个创建于 2578 天前的主题，其中的信息可能已经有所发展或是发生改变。

    1. 代码

      fn main() { println!("Hello world!"); }

    2. rustc main.rs 报错 error: couldn't load codegen backend "/usr/local/lib/rustlib/i686-apple-darwin/codegen-backends/librustc_codegen_llvm-llvm.dylib": "dlsym(RTLD_DEFAULT, CFURLConnectionCreateWithProperties): symbol not found"

    3. 系统：MacOS，rustc 1.30.1，gcc：Apple LLVM version 8.0.0 (clang-800.0.42.1)

  • rustc
  • main
