如何修复 Docker 依赖项安装？

Question

我有一个电影推荐系统，我正在尝试为它创建一个 docker 映像。

requirements.txt

pandas==0.22.0
requests==2.18.4
Django==2.0.6
Scrapy==1.5.1
numpy==1.14.0
scipy==1.0.0
pymongo==3.7.2

Dockerfile：

FROM python:3
MAINTAINER SPARSH KEDIA

ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt

RUN mkdir /app
WORKDIR /app
COPY ./app /app

RUN adduser -D user
USER user

在运行 docker build 时，它显示以下错误：

error: Command "gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE=1 -D_LARGEFILE64_SOURCE=1 -Inumpy/core/include -Ibuild/src.linux-x86_64-3.7/numpy/core/include/numpy -Inumpy/core/src/private -Inumpy/core/src -Inumpy/core -Inumpy/core/src/npymath -Inumpy/core/src/multiarray -Inumpy/core/src/umath -Inumpy/core/src/npysort -I/usr/local/include/python3.7m -Ibuild/src.linux-x86_64-3.7/numpy/core/src/private -Ibuild/src.linux-x86_64-3.7/numpy/core/src/npymath -Ibuild/src.linux-x86_64-3.7/numpy/core/src/private -Ibuild/src.linux-x86_64-3.7/numpy/core/src/npymath -Ibuild/src.linux-x86_64-3.7/numpy/core/src/private -Ibuild/src.linux-x86_64-3.7/numpy/core/src/npymath -c numpy/random/mtrand/mtrand.c -o build/temp.linux-x86_64-3.7/numpy/random/mtrand/mtrand.o -MMD -MF build/temp.linux-x86_64-3.7/numpy/random/mtrand/mtrand.o.d" failed with exit status 1

The command '/bin/sh -c pip install -r /requirements.txt' returned a non-zero code: 1

如何解决这个错误？或者有其他方法可以下载 requirements.txt 吗？

我使用 macOS HighSierra 10.13.2。

我是 docker 新手，请帮忙。

Answer 1

看起来是与numpy 相关的问题，可能是由于库setuptools 和wheel 构建所致。

添加到要求：

pip==19.0.2
setuptools==40.6.3
wheel==0.32.0

以下此链接是为与 AWS SageMaker 一起使用而开发的，但也许可以帮助您：

Dockerfile

Answer 2

这与 Docker 无关。 numpy、scipy等包需要在系统上安装gcc和python-dev包。

尝试在 Dockerfile 中添加apt-get install -y python-dev 作为步骤。

PS：这些库可能还有其他系统包依赖项。请检查并安装它们。
