Docker中Python3.7安装Scipy遇sys/endian.h缺失错误求助

Hey there, let's work through this Scipy install issue you're facing! That missing sys/endian.h error is a classic system dependency hiccup, especially with early preview versions of Python like 3.7.0a4. Here are a few actionable fixes to try:

1. Install the missing system header package #

The sys/endian.h file is part of the libc6-dev package, which might not be included in the minimal Python 3.7.0a4 Docker image. Add it to your apt-get install command:

apt-get update && \
apt-get -y install \
libblas-dev \
liblapack-dev \
libatlas-base-dev \
gfortran \
libc6-dev

Then run pip install scipy again.

2. Pin Scipy to a version compatible with Python 3.7.0a4 #

Python 3.7.0a4 is an early alpha release, and newer Scipy versions have dropped support for it. Try installing an older, compatible version of Scipy:

pip install scipy==1.1.0

This version was released around the time Python 3.7 was in preview, so it should play nice with the alpha build.

3. Explicitly set the header file path for the compiler #

If the header exists but the compiler can't locate it, force the include path with CFLAGS:

CFLAGS="-I/usr/include" pip install scipy

This tells the C compiler to look in /usr/include (where sys/endian.h lives) for required system headers.

4. Switch to a more complete base image #

The official python:3.7.0a4 image might be stripped down to save space. Try using a full Debian/Ubuntu base image and installing Python 3.7.0a4 manually:

docker run --rm -it debian:stretch bash
apt-get update && apt-get -y install python3.7-dev libblas-dev liblapack-dev libatlas-base-dev gfortran libc6-dev
pip3.7 install scipy

Why this works in Python 3.6? #

The Python 3.6 Docker image is based on a mature, stable environment with all necessary system dependencies pre-configured, and Scipy maintains full support for Python 3.6 across most versions. The early alpha Python 3.7 image just doesn't have the same level of polish or pre-configured compatibility yet.
