python:3-8.alpine我正在尝试使用 python 模块构建基于 的图像asyncpg。

这是我的 Dockerfile 的一部分：

FROM python:3.8-alpine

RUN apk add gcc
RUN apk add python3-dev

RUN pip3 install asyncpg

我添加了gcc，python3-dev因为我认为我需要它们能够asyncpg根据文档进行构建：https ://magicstack.github.io/asyncpg/current/installation.html （但我不确定，我想我应该无需构建此模块即可安装）

但是在构建图像时出现以下错误：

gcc -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -DTHREAD_STACK_SIZE=0x100000 -fPIC -I/usr/local/include/python3.8 -c asyncpg/pgproto/pgproto.c -o build/temp.linux-x86_64-3.8/asyncpg/pgproto/pgproto.o -O2 -fsigned-char -Wall -Wsign-compare -Wconversion
In file included from asyncpg/pgproto/pgproto.c:29:

    11 | #include <limits.h>
       |          ^~~~~~~~~~
compilation terminated.
error: command 'gcc' failed with exit status 1

如何解决此错误并安装asyncpg？

谢谢

您必须安装构建工具而不仅仅是 gcc。您也可以删除RUN apk add python3-dev步骤。由于您使用 python 作为基础图像。

FROM python:3.8-alpine

RUN apk add --no-cache build-base

RUN pip3 install asyncpg

构建标准输出

您忘记添加musl-dev库。这是工作的 Dockerfile

FROM python:3.8-alpine

RUN apk add gcc python3-dev musl-dev

RUN pip3 install asyncpg
