找不到与scipy Docker匹配的分发

对接机

FROM python:3.8-alpine
MAINTAINER ABC

ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt /requirements.txt
RUN apk add gcc freetype-dev
RUN apk add gfortran musl-dev g++ libgcc libquadmath musl libgfortran
RUN apk add lapack-dev

RUN apk add libffi-dev libxslt-dev mariadb-dev build-base --virtual --no-cache && \
    pip install -U  cffi pip setuptools && \
    pip3 install --upgrade pip --no-cache-dir wheel  -r requirements.txt

RUN mkdir /code
WORKDIR /code
COPY ./code /code

在我写的requirements.txt中

scipy==1.5.2

出现错误

ERROR: No matching distribution found for scipy==1.5.2
ERROR: Service 'web' failed to build: The command '/bin/sh -c apk add libffi-dev libxslt-dev mariadb-dev &&     pip install -U  cffi pip setuptools &&     pip3 install --upgrade pip --no-cache-dir wheel  -r requirements.txt' returned a non-zero code: 1

如何消除此错误？

您错过了用于安装scipy的blas软件包，接下来是用于安装scipy的最小Dockerfile软件包，仅供参考：

停靠文件：

FROM python:3.8-alpine

RUN apk add build-base openblas-dev && \
    pip3 install numpy scipy==1.5.2

RUN python3 -c "import scipy; print(scipy.__version__)"

执行日期：
