Question

from alpine:latest
RUN apk add --no-cache python3-dev \
    && pip3 install --upgrade pip

WORKDIR /backend
COPY . /backend

RUN pip --no-cache-dir install -r requirements.txt
EXPOSE 5000
ENTRYPOINT ['python3']
CMD ['app.py']

我有一个类似于上面的简单Dockerfile。

当我做docker build -t backend:latest .时，它会给我

ERROR: Command errored out with exit status 1: /usr/bin/python3.7 /usr/lib/python3.7/site-packages/pip install --ignore-installed --no-user --prefix /tmp/pip-build-env-wr55ljb4/overlay --no-warn-script-location --no-binary :none: --only-binary :none: -i https://pypi.org/simple -- 'setuptools>=40.8.0' wheel 'cffi>=1.1; python_implementation != '"'"'PyPy'"'"'' Check the logs for full command output.
The command '/bin/sh -c pip --no-cache-dir install -r requirements.txt' returned a non-zero code: 1

似乎我的点子无法正常工作。有什么想法吗？

Answer 1

我也为此挣扎了一下。我最终用

创建了我的容器

FROM python:3.7-alpine

RUN apk update && apk add gcc libc-dev make git libffi-dev openssl-dev python3-dev libxml2-dev libxslt-dev

无论如何，如果您想使用alpine:latest，则可能只需要上面列出的一些os依赖项。

Answer 2

PyPy不支持Python3.7：

PyPy是Python的一种快速，兼容的替代实现语言（2.7.13和3.5.3、3.6）

source

您的问题是安装cffi所需的PyPy：

CPython 2.6或2.7或3.x或PyPy（最早的版本为PyPy 2.0 CFFI;或适用于CFFI 1.0的PyPy 2.6）。

请参阅this

所以您需要安装CPython 3.x或将python降级到3.6，应该可以解决此问题

最简单的方法将alpine:latest替换为python:3.6-alpine3.9
