Dockerfile中的pip安装失败 [英] pip install in Dockerfile is failing

问题描述

我为我的应用创建了一个Dockerfile，如下所示，但是当我尝试构建dockerimage时失败了.

Hi I have created a Dockerfile for my app as below but it failed when I try to build the dockerimage .

FROM python:alpine3.7
COPY . /app
WORKDIR /app
RUN pip install --upgrade pip
RUN pip install -r requirements.txt
CMD python ./index.py

这是requirements.txt的内容

here is the content of requirements.txt

flask
numpy
pandas 
SQLAlchemy
pyodbc

在开始运行pip install -r requirements.txt时 它可以安装flask，但是在numpy和pandas之间看起来像，它开始在许多页面中产生错误.

when it gets to RUN pip install -r requirements.txt it can install flask but after that look like between numpy and pandas it start to generate error for many many pages.

有什么帮助吗?
