Python 在Apple Silicon上运行的Big Sur上安装加密时出错

我试着在我的全新Air M1上安装加密技术。但是出了点问题。 我已经尝试过谷歌的一些解决方案，但没有效果

环境详情：

• Python 3.9.1
• pip 21.0.1
• macOS BigSur 11.2应用程序1 M1
• cffi==1.14.5
• openssl@1.1

复制步骤：

pip3安装加密技术

      =============================DEBUG ASSISTANCE=============================
      If you are seeing a compilation error please try the following steps to
      successfully install cryptography:
      1) Upgrade to the latest pip and try again. This will fix errors for most
         users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
      2) Read https://cryptography.io/en/latest/installation.html for specific
         instructions for your platform.
      3) Check our frequently asked questions for more information:
         https://cryptography.io/en/latest/faq.html
      4) Ensure you have a recent Rust toolchain installed:
         https://cryptography.io/en/latest/installation.html#rust
      5) If you are experiencing issues with Rust for *this release only* you may
         set the environment variable `CRYPTOGRAPHY_DONT_BUILD_RUST=1`.

Rust目前在m1通孔上工作

curl--proto'=https'--tlsv1.2-sSfhttps://sh.rustup.rs |sh

但是，在修复锈迹后，您很可能会遇到另一个错误

导入_cffi_后端作为后端 导入错误：dlopen（/private/var/folders/fd/s3rl30nj6790c3p5df6x2_700000gn/T/pip-build-env-w44a7bqz/overlay/lib/python3.x/site-packages//cffi\u backend.cpython-3X-darwin.so，2）：未找到合适的图像。确实发现： /private/var/folders/fd/s3rl30nj6790c3p5df6x2_700000gn/T/pip-build-env-w44a7bqz/overlay/lib/python3.X/site-packages//cffi_backend.cpython-3X-darwin.so:mach-o，但架构错误

这里讨论的问题是，CFFI维护人员不支持m1 Mac：

在新的更新之后，它对我有效

sudo xcode-select --install.

我认为最近，python加密模块需要Rust来编译。从长远来看，这将带来巨大的好处，但据报道，过渡过程比可能的更为坎坷……因此我必须等待m1何时支持它？看起来锈现在支持m1，所以应该只是设置它的问题。我不是问这个问题的合适人选，不过……你可以尝试更合适的解决方案：我在萨比克最后一次评论后安装了锈迹，这就解决了问题。谢谢你们！
