python - django-allauth python :3. 8.3-alpine Dockerfile 的依赖项是什么

Question

我有一个为 django 项目定义的 Dockerfile、docker-compose.yml、requirements.txt。 Dockerfile 使用python:3.8.3-alpine，docker-compose.yml 有一个使用postgres:12.0-alpine 镜像的数据库服务。我确保 Dockerfile 中按要求定义了依赖项。但是，在我看来 django-allauth 需要额外的依赖项。我已经尝试了好几天来解决这个问题，但收到一条错误消息
此软件包需要 Rust >=1.41.0。 错误:密码学构建轮失败。我粘贴了整个错误以供引用。任何帮助都感激不尽。提前致谢。

      =============================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`.
      =============================DEBUG ASSISTANCE=============================
  
  error: can't find Rust compiler
  
  If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.
  
  To update pip, run:
  
      pip install --upgrade pip
  
  and then retry package installation.
  
  If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.
  
  This package requires Rust >=1.41.0.

  ERROR: Failed building wheel for cryptography

Answer 1

使用Python:3.8.2-alpine 在需求中添加cryptography==3.1.1 在 Dockerfile 中

CRYPTOGRAPHY_DONT_BUILD_RUST 1
RUN apk update \
    && apk add postgresql-dev gcc python3-dev musl-dev \
    && apk add libffi-dev openssl-dev cargo

这对我有用，但要做好准备，你的 docker 镜像将达到 +300~500 MB
