python - 无法在 Alpine Docker容器上安装pyorc

Question

获取编译错误-取决于ORC二进制文件。

In file included from src/_pyorc/_pyorc.cpp:1:
src/_pyorc/Reader.h:7:10: fatal error: 'orc/OrcFile.hh' file not found
#include "orc/OrcFile.hh"
         ^~~~~~~~~~~~~~~~
1 error generated.
error: command 'clang' failed with exit status 1

如果我也分别编译 apache-orc ，那么我该如何将其引用给PyOrc Pip安装？
任何人都有任何解决方案或想法，我们如何才能在 Alpine 容器中安装 pyorc 软件包。
我在使用ubuntu的 Alpine 图像和正常的python docker图像工作正常时遇到问题。
Docker镜像:FROM python:3.7-alpine

Answer 1

我使用了Docker多阶段构建:

# Dockerfile

FROM python:3.7.3
WORKDIR /app
RUN pip install pyorc -t .

FROM python:3.7.3-alpine
WORKDIR /app
RUN apk add --no-cache --virtual .build-deps g++ musl-dev gcompat
COPY --from=0 /app .

似乎可行:

$ docker build -t test .
$ docker run -it --rm test python
