django-allauth python:3.8.3-alpine Dockerfile 的依赖项是什么

Question

我在下面为 Django 项目定义了一个 Dockerfile，docker-compose.yml，requirements.txt。 Dockerfile 使用 python:3.8.3-alpine 并且 docker-compose.yml 有一个使用 postgres 的数据库服务： 12.0-高山图像。我确保已根据需要在 Dockerfile 中定义依赖项。然而，在我看来 django-allauth 需要额外的依赖。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
此包需要 Rust >=1.41.0。错误：加密轮子构建失败 。为了参考起见，我粘贴了整个错误。任何帮助都感激不尽。提前致谢。

      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  If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it.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.

Answer 1

django-allauth 需要 cryptography 而 now requires Rust to compile。您可以尝试使用较新的 python 版本更新您的 Dockerfile，即 FROM python:3.8.8-alpine，这可能会让它获取用于加密的预构建二进制文件。

如果这不起作用，您需要添加 Rust 依赖项，以便它可以编译包。

# install dependencies
RUN apk update \
    && apk add postgresql-dev gcc python3-dev musl-dev \
    && apk add libffi-dev libressl-dev \
    && apk add --no-cache jpeg-dev zlib-dev libjpeg \
    && apk add rust cargo # ADDED LINE

Answer 2

使用python:3.8.2-alpine 添加 cryptography==3.1.1 in requirements 在 Dockerfile

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，但请准备好您的 docker 图片将超过 300~500 MB
