使用pyspark lib构建docker映像时出现问题 [英] Problem in building a docker image with pyspark lib

问题描述

我正在尝试使用s2i和Jenkins构建docker映像.我在requirement.txt文件

I'm trying to build a docker image using s2i and Jenkins. I have the following dependencies in the requirement.txt file

scikit-learn==0.21.2
scipy==0.18.1
pandas==0.24.2
seldon-core==0.3.0
pypandoc
pyspark==2.4.1

但是当我尝试使用以下错误消息安装pyspark时，我的构建过程失败了

But my build process fails when it tries to install pyspark with the following error message

尽管我在requirments.txt文件中的pyspark之前列出了pypandoc，但是看起来像在安装pyspark时，尚未安装pypandoc.有什么问题吗?

although I have listed pypandoc before pyspark in the requirments.txt file, but it looks like when it's installing pyspark, pypandoc is not installed yet, which is a dependency. What's the problem?

推荐答案

我通过执行以下错误来传递此错误:

I passed this error by executing:

pip install pypandoc

在安装pyspark之前.我尝试了很多在Requires.txt中使用pypandoc == 1.4的方法，但是它不起作用.

before installing pyspark. I tried a lot use pypandoc==1.4 in requirements.txt but it doesn't work.

在这种情况下，人们使用相同的方式: https://hub.docker.com/r/takaomag/test-0/dockerfile https://www.ibm.com/support/Knowledgecenter/el/SSWTQQ_2.0.3/install/t_si_pythonpackagesoffline.html 无法安装pyspark

In that sources people using same way: https://hub.docker.com/r/takaomag/test-0/dockerfile https://www.ibm.com/support/knowledgecenter/el/SSWTQQ_2.0.3/install/t_si_pythonpackagesoffline.html unable to install pyspark
