我尝试在我的 alpine docker 镜像中使用 pip 安装 pyarrow,但 pip 无法找到该包。
我正在使用以下 Dockerfile:
FROM python:3.6-alpine3.7
RUN apk add --no-cache musl-dev linux-headers g++
RUN pip install pyarrow
输出:

社区中有人能够在 alpine 容器中安装 pyarrow 吗?
正如 Wes 上面所说,你必须从源代码构建,但甚至从源代码构建也存在一些问题,现在我们有一个解决方案。

不,据我所知。目前我们只为 Linux 用户提供基于 glibc 的 Python 轮子。要在 Alpine Linux 上使用 pyarrow,您需要从源代码构建——不过,我不知道有人在这个平台上测试过该库。
从 Alpine Linux 3.17 版本开始,如果您对特定版本没问题,可以将
pyarrow
安装为系统 package。这应该比从源代码构建要容易得多。如果您使用的是 virtualenv,则可以在安装软件包后将文件复制到其中,例如对于 v.3.20:
RUN apk add --no-cache py3-pyarrow=16.1.0-r0 && \
rm -rf /var/cache/apk/* && \
cp -rv /usr/lib/python3.12/site-packages/pyarrow* ${VIRTUAL_ENV}/lib/python3.12/site-packages/
其他需要大量构建的 Python 包也可以通过这种方式安装,例如
numpy
、
scipy
、pandas
等为了保持较小的图像大小,请使用多阶段构建并从构建阶段仅复制Python包,留下任何构建依赖项。
