在构建Docker映像时尝试安装sklearn（scikit-learn）时，它失败。
这些是Dockerfile的处理后的行：
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
一切顺利，直到最后一行。在那里，它首先要花很长时间，然后发生错误。这是日志：
