python slim 或 alpine docker 镜像无法使用 pipenv 安装软件包

Question

我正在尝试为我的 python 应用程序构建一个 docker 容器，但是在通过 pipenv 安装 python 包时遇到了问题。
如果我将基本图像设置为 python:3.8.5但是，如果我设置了 -slim，它会起作用版本或 -alpine版本失败并出现以下错误:

更新:
添加包进行编译后，这次我得到了不同的错误，现在运行也需要很长时间。

可以将问题最小化为 Dockerfile

FROM python:3.8.5-slim
RUN pip install --no-cache-dir brotlipy

如果你运行这个，你会得到错误

...
unable to execute 'gcc': No such file or directory
error: command 'gcc' failed with exit status 1
...

-slim和 -alpine图像不包括 C 编译器，而 python:3.8.5图像。如果您安装 C 编译器，您可能会遇到其他错误，例如缺少 limit.s , ffi.h ，以及 C++ 标准库。
这是一个使用 -alpine 的最小工作示例图片。

FROM python:3.8.5-alpine
RUN apk add gcc g++ libffi-dev musl-dev \
    && python -m pip install --no-cache-dir brotlipy \
    && apk del gcc g++ libffi-dev musl-dev

这是 -slim 的完整示例图片。使用 pipenv run python运行 spacy 部分。

FROM python:3.8.5-slim

ARG DEBIAN_FRONTEND="noninteractive"

RUN pip install pipenv

WORKDIR /app

COPY ./ /app/

RUN apt-get update \
    && apt-get install --yes --no-install-recommends \
        gcc g++ libffi-dev \
    && pipenv install --sequential --deploy --verbose \
    && apt-get autoremove --yes gcc g++ libffi-dev \
    && rm -rf /var/lib/apt/lists/*

RUN pipenv run python -m spacy download en_core_web_sm

RUN pipenv install gunicorn[gevent]
