Question

我正在尝试在运行gunicorn的docker python：3.8.0a4-alpine3.9上安装Gevent。

构建docker时，总是会收到错误消息“ gcc失败，退出状态为1”。

我尝试安装多个软件包，但没有一个起作用。

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：

这是我正在运行的Gunicorn命令：

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

您对如何使用此版本的python alpine安装Gevent有任何想法吗？

编辑- 它成功安装在Apline和python的最新版本上-FROM python：3.7-alpine3.8

Answer 1

ailpine映像需要在libs下安装以构建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 2

对我来说，以上都不适用于 python:3.8-alpine。这样做了：

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

Answer 3

我通过添加将 gevent==21.1.2 与 python:3.9.4-alpine 结合使用

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

它就像一个魅力！

Answer 4

请参阅this，几年前，人们想在python3.7上安装并遇到问题，并且在去年进行了修复，以使gevent支持python3.7。

所以，我想gevent团队需要付出更多的努力来适应每个python版本，因为其原理是为python制作一些monkey patch。

并且，从当前的official announcement开始，它说：

gevent 1.5在Python 2.7.9及更高版本以及Python 3.5、3.6和3.7上运行。

它没有提到3.8，所以绝对需要等待。
