Question

我已经用Alpine linux构建了一个docker镜像。

在我的Dockerfile中，以下一行

RUN apk add --update py-numpy py-numpy-dev  py-scipy  py-numpy-f2py --repository http://dl-cdn.alpinelinux.org/alpine/v3.8/community

我看到一些与

相似的日志消息

fetch http://dl-cdn.alpinelinux.org/alpine/v3.8/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.8/community/x86_64/APKINDEX.tar.gz

(3/3) Installing py2-numpy (1.14.3-r1)
Executing busybox-1.28.4-r1.trigger
OK: 389 MiB in 104 packages

但是当我运行docker映像并放入python并运行

将numpy导入为np

我得到

ImportError: No module named numpy

此处是完整的终端会话

/app # python
Python 2.7.15 (default, Sep 12 2018, 02:38:23) 
[GCC 6.4.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numpy
>>>

所以我对为什么无法获取apk包感到有些困惑？

任何想法都会受到赞赏。

干杯，泰勒

完整的Dockerfile。

注意：我也在Pandas和scipy上挣扎，所以正在网上查看其他docker文件，我敢肯定这可以清除一点。

从Alpine Repository安装了python软件包，但在python中不可用
