Install pandas in a Dockerfile

Alpine don't contain build tools by default. Install build tool and create symbolic link for locale:

$ apk add --update curl gcc g++
$ ln -s /usr/include/locale.h /usr/include/xlocale.h
$ pip install numpy

I realize this question has been answered, but I have recently had a similar issue with numpy and pandas dependancies with a dockerized project. That being said, I hope that this will be of benefit to someone in the future.

My solution:

As pointed out by Aviv Sela, Alpine does not contain build tools by default and will need to be added though the Dockerfile. Thus see below my Dockerfile with the build packages required for numpy and pandas for be successfully installed on Alpine for the container.

FROM python:3.6-alpine3.7

RUN apk add --no-cache --update \
    python3 python3-dev gcc \
    gfortran musl-dev g++ \
    libffi-dev openssl-dev \
    libxml2 libxml2-dev \
    libxslt libxslt-dev \
    libjpeg-turbo-dev zlib-dev

RUN pip install --upgrade pip

ADD requirements.txt .
RUN pip install -r requirements.txt

The requirements.txt

numpy==1.17.1
pandas==0.25.1

EDIT:

Add the following (code snippet below) to the Dockerfile, before the upgrade pip RUN command. It is critical to the successful installation of pandas as pointed out by Bishwas Mishra in a comment.

RUN pip install --upgrade cython
