I'm having some trouble installing the python cryptography package on my raspberry pi, specifically with python version 3.9.8 (installed with pyenv). The cryptography package is installed on my system using pacman (python-cryptography package), and thus works using the main python interpreter (3.10.1). However, I need some version of python 3.9 specifically for another package I am using in this project. Any time I try to install cryptography through the python 3.9.8 environment, I get the following error:

我在我的raspberry pi上安装python密码软件包时遇到了一些问题，特别是python版本3.9.8（与pyenv一起安装）。密码包是使用pacman（python-cryptography package）安装在我的系统上的，因此使用主要的python解释器（3.10.1）工作。然而，我需要一些版本的python 3.9专门用于我在这个项目中使用的另一个包。每当我尝试通过python 3.9.8环境安装密码学时，我都会得到以下错误：

      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/ for specific

✘ Installation Failed

So far I have tried:

到目前为止，我已经尝试过：

1. Upgrading pip (now version 21.3.1)


2. Ensuring a rust compiler is installed (rustc version 1.57.0)


3. Ensure libffi is installed (version 3.4.2)


4. Ensure OpenSSL is installed (version 1.1.1)


5. Being an Arch Linux system, I of course have gcc installed for a C compiler (version 10.2.0)


6. Isolated the issue down to this package (I was initially trying to install cryptography as a dependency for msal)


7. Tried using pipenv as well as navigating directly to the python executable in the ~/.pyenv/versions/3.9.8 directory


8. In the ~/.pyenv/versions/3.9.8 directory, tried both using the pip executable there, as well as ./python -m pip for installation, with the same results both times.


9. The above steps also included checking all 4 of the suggested debugging steps from the error message.

It might also be useful to note that all of this works perfectly in the virtual environment on my main system (also Arch Linux, but x86_64 rather than ARM).

还需要注意的是，所有这些在我的主系统(也是Arch Linux，但x86_64而不是ARM)上的虚拟环境中都能完美地工作。

What else can I try to get the cryptography package installed?

我还可以尝试安装加密包吗？

Alternatively, it looks like the same version of the library is installed in the main site packages through pacman, but that of course is not recognized by the virtual environment or by a separate version of python. Is there some way I can force python 3.9.8 to use that package instead?

或者，它看起来像是通过Pacman在主站点包中安装了相同版本的库，但虚拟环境或单独版本的Python当然不能识别该库。有没有什么方法可以强制python3.9.8使用该包呢？

@jakub's solution ended up solving the problem for me. I uninstalled the version of rust that was installed through pacman. To replace it, I installed rustup and then using rustup, installed the latest nightly version of rust (1.60). Once I did that, installing the cryptography package worked just fine.

@Jakub的解决方案最终为我解决了问题。我卸载了通过吃豆人安装的铁锈版本。为了取代它，我安装了Rustup，然后使用Rustup安装了最新的夜间版本的Ruust(1.60)。一旦我这样做了，安装加密包就可以很好地工作了。

If you are using rustup, just make sure that you add ~/.cargo/bin to your PATH before installation. Also, the command I used to install rust through rustup was rustup toolchain install nightly.

如果您使用的是Rustup，只需确保在安装之前将~/.cargo/bin添加到路径中。另外，我用来通过Rustup安装Ruust的命令是Rustup工具链每晚安装。
