Can't install wheels on docker for numpy-CodePudding

this is my first time running Docker and I am having issues creating the image. This is the code inside my docker file

FROM alpine:latest

ENV PATH /usr/local/bin:$PATH

RUN apk add --no-cache python3 py3-pip
RUN apk add py3-pip && pip3 install --upgrade pip

WORKDIR /backend

COPY . /backend

RUN pip3 install wheel
RUN pip3 install numpy
RUN pip3 --no-cache-dir install -r requirements.txt

Under requirements.txt, I have numpy==1.23.1.

The relevant error codes are

#12 8.606   Building wheel for numpy (pyproject.toml): started
#12 22.30   Building wheel for numpy (pyproject.toml): finished with status 'error'

#12 22.34 ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects
------
executor failed running [/bin/sh -c pip3 install numpy]: exit code: 1

I tried searching for solutions but they mentioned that once you upgraded PIP, things should install fine. In this case, they still do not work well.

Do give any advice!

CodePudding user response：

Try pip3 install --extra-index-url https://alpine-wheels.github.io/index numpy isntead. Does that work? If so, I can explain in an answer
