在 Docker Alpine Python 中安装 gevent 时出错

Question

我正在尝试在 docker 图像 python:3.8.0a4-alpine3.9 上安装 gevent，它是运行 gunicorn。

构建 docker 时，我总是收到错误“gcc 失败，退出状态为 1”。

我尝试安装了几个软件包，但 none 成功了。

这是 Dockerfile：

FROM python:3.8.0a4-alpine3.9

RUN echo "@edge-community http://dl-cdn.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories && \
  apk update && \
  apk add build-base python-dev && \
  apk add py-gevent

RUN pip install gunicorn gevent

命令： docker build . -t "test:one"

最后几行输出：

这是我的 Gunicorn 命令运行:

gunicorn web.wsgi:application --bind 0.0.0.0:8000  --worker-connections 1000 --workers 6 -k gevent

对于如何使用此版本的 python alpine 安装 Gevent，您有什么想法吗？

编辑 - 它在最新版本的 Alpine 和 python - FROM python:3.7-alpine3.8.

上成功安装

Answer 1

请参阅 this，几年前，有人想在 python3.7 上安装并遇到问题，去年进行了修复以使 gevent 支持 python3.7.

所以，我猜 gevent 团队需要额外的努力来适应每个 python 版本，因为它的原则是为 python.

制作一些 monkey patch

而且，从目前的 official announcement，它说：

gevent 1.5 runs on Python 2.7.9 and up, and Python 3.5, 3.6 and 3.7.

它没有提到3.8，所以你肯定需要等待。

Answer 2

ailpine 镜像需要安装在 libs 下面来构建 gevent。
RUN apk add --no-cache python3-dev libffi-dev gcc musl-dev make
this docker file 可能有助于测试

Answer 3

对我来说 none 以上与 python:3.8-alpine 一起工作。工作了这个：

RUN apk --update --no-cache add python3-dev libffi-dev gcc musl-dev make libevent-dev build-base

Answer 4

我通过添加

将 gevent==21.1.2 与 python:3.9.4-alpine 一起使用

RUN apk update \
   && apk add --no-cache build-base

效果非常好！

Answer 5

好消息：从gevent 21.12.0（2021-12-11发布）开始，pypi上有一个musllinux镜像，所以没有缺失的依赖，它将从轮子安装。在 python3.10-alpine 上验证 pip install gevent 工作正常。哇哦！

历史答案，见下文。

只是在这里添加：对于 python:3.9-alpine（目前是 python3.9.9 + alpine 3.14.3），我需要以下 Gevent 21.1.0：

RUN apk add --no-cache build-base libffi-dev

希望他们添加对通过 pip 在 Alpine 上安装的支持，因为最近有一个 PEP 应该可以使这更容易。我在这里开了一个问题：https://github.com/gevent/gevent/issues/1837
