我想用apk在Alpine Linux中安装一些Python包。我用numpy作为下面的例子。

文档文件FROM python:3-alpine

RUN apk add --update py3-numpy

我建立我的码头形象$ docker build -t python-numpy .

运行它并尝试用python导入包$ docker run -it --rm python-numpy python -c "import numpy"

Traceback (most recent call last):

File "", line 1, in

ModuleNotFoundError: No module named 'numpy'

但是，没有找到。在apk add --update py3-numpy之后运行pip install numpy不考虑apk包py3-numpy并下载另一个版本：Collecting numpy

...

如果我指定的版本与pip install numpy==1.16.4-r1中的py3-numpy(参见docker build的输出)相同，则会导致Collecting numpy==1.16.4-r1

我错过了什么？
