ImportError No module named Image in Jenkins

[Cherry Tsai]

Hi guys,

I had python trouble. I want to compare two images using python in Jenkins.

When I added "import Image" or "from PIL import Image" in my script, it will show error message "ImportError: No module named Image".

But use "import os, time", it was working.

Basic environment:

1. use docker official jenkins

2. python 2.7

3. PYTHONPATH is /usr/lib/python2.7/dist-packages/PIL
   /usr/lib/python2.7/dist-packages/PIL

4. Sys.path is ['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat']

Please help me how to solve it?

I would guess that the official Jenkins docker image does not include the Python imaging library by default.  You probably need to install the python imaging library by adding an entry to your Dockerfile:

RUN apt-get update && apt-get install -y python-imaging

You may also need to refer to http://askubuntu.com/questions/156484/how-do-i-install-python-imaging-library-pil

Must be use Dockerfile install? I used manually install in Jenkins container.

I tried to run command in Jenkins container:

$ python
$ from PIL import Image

It's working for me.

Then I checked Python2.7 path, it has PIL and Image folder in /usr/local/lib/python2.7.

But only Jenkins couldn't use Python PIL and Image. I'm very confused.

Your results seem different from mine.  The commands I executed:

$ docker run -i --rm -p 8080:8080 -p 50000:50000 jenkins /bin/bash

python

print 1 + 1

print 2 + 2

from PIL import Image

^D

2

4

Traceback (most recent call last):

  File "<stdin>", line 5, in <module>

ImportError: No module named PIL

As far as I can tell, that means the PIL module is not available in the docker image named "jenkins".

Hi Mark,

I found the other solution. First, I install "Python Plugin" in Jenkins platform. And I can write the script in Jenkins configuration -> Execute Python script.

Now I can use Python package "Image", compare two images.
