python - 构建docker镜像时无法安装sklearn

Question

当我在构建 docker 镜像时尝试安装 sklearn (scikit-learn) 时，它失败了。

这些是 Dockerfile 的处理行:

FROM amancevice/pandas:0.25.0-alpine

RUN apk update
RUN apk add build-base
RUN apk add gcc musl-dev libc-dev util-linux-dev linux-headers python3-dev postgresql-libs postgresql-dev git libffi-dev libmemcached-dev zlib-dev ca-certificates zlib-dev jpeg-dev freetype-dev libpng

RUN pip3 install --upgrade pip
RUN pip3 install scikit-learn

一切都很顺利，直到最后一行。在那里，它首先需要永远，然后发生错误。这是日志:
