如果您看到编译错误，请尝试以下步骤以成功安装cryptography：
1）升级到最新的pip并重试。这将修复大多数用户的错误。请参阅：https://pip.pypa.io/en/stable/installing/#upgrading-pip
2）阅读https://cryptography.io/en/latest/installation/了解特定平台的具体说明。
3）查看我们的常见问题解答以获取更多信息：https://cryptography.io/en/latest/faq/
4）确保您安装了最新的Rust工具链：https://cryptography.io/en/latest/installation/#rust

✘ 安装失败
到目前为止，我尝试过以下方法：
- 升级pip（现在版本为21.3.1）
- 确保安装了rust编译器（rustc版本为1.57.0）
- 确保安装了libffi（版本为3.4.2）
- 确保安装了OpenSSL（版本为1.1.1）
- 作为Arch Linux系统，我当然安装了C编译器gcc（版本为10.2.0）
- 将问题隔离到此包（最初我尝试安装
作为 的依赖项） - 尝试使用pipenv以及直接导航到<~/.pyenv/versions/3.9.8>目录中的python可执行文件
- 在<~/.pyenv/versions/3.9.8>目录中，尝试使用pip可执行文件，以及<./python -m pip>进行安装，两次结果都相同。
- 上述步骤还包括检查错误消息中建议的4个建议的调试步骤。
值得注意的是，在我的主系统的虚拟环境中，所有这些都可以完美运行（同样是Arch Linux，但是x86_64而不是ARM）。
我还可以尝试什么来安装
或者，看起来在通过
