我在执行我编写的rust库中的测试时遇到了一些问题。cargo check和cargo build运行时没有问题，但当我尝试执行程序时，我遇到了一个链接器错误，我在解密时遇到了一些问题。

我怀疑这是我在MacOS上的开发环境的一些问题，我最近从Linux迁移到了MacOS，它在Linux上运行良好，在GitLab上建立的持续集成运行测试没有问题。

尝试使用不同的rustup安装程序，通过官方的rust安装脚本、nikpkg和自制程序。每个都有相同的问题。
如果有人能提供任何建议，我们将不胜感激！谢谢
您可以尝试使用x86_64-apple-darwin版本的rust。
我从中找到了这个方法，它解决了我的问题。
