Question

我正在尝试使用pip在我的alpine docker图像中安装pyarrow，但是pip无法找到包。

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：

有没有社区能够在高山容器中安装pyarrow？

Answer 1

不，不是我知道的。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，你需要从源码构建 - 我不知道有人在这个平台上测试过这个库。

Answer 2

正如Wes上文所述，您必须从源代码构建，但是即使从源代码构建也存在一些问题，现在我们有了solution。
