Google App Engine, Library PIL, Image, The _imaging C module is not installed

[Dennis Hafemann]

Hi there,

I am on project using Google App Engine and third party library PIL.

Currently I am trying to just create a new image, via PIL's submodule Image. 

So my local installation with Python 2.7.4 running works just finde with PIL:

$ python

Python 2.7.4 (default, Apr 19 2013, 18:28:01) 

[GCC 4.7.3] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> from PIL import Image

>>> img=Image.new("RGBA", (100, 100))

>>> if img: print True

... 

True

>>> 

My app.yaml, includes following libraries-information:

...
runtime: python27
...
libraries:

- name: PIL

  version: latest

I deployed my application being convident having it running. ... but ... the online-version of Google App Engine logged some errors:

...
    img=Image.new("RGBA", (width, height))

  File "/base/data/home/runtimes/python27/python27_lib/versions/third_party/PIL-1.1.7/PIL/Image.py", line 1763, in new

    return Image()._new(core.fill(mode, size, color))

  File "/base/data/home/runtimes/python27/python27_lib/versions/third_party/PIL-1.1.7/PIL/Image.py", line 37, in __getattr__

    raise ImportError("The _imaging C module is not installed")

ImportError: The _imaging C module is not installed

(... and to make sure, I tried "version: 1.1.7" in my app.yaml).

I also tried importing _imaging from my local python-installation, but didn't get it running. I neither find anything helpful about this.

Does anyone have a helpful tipp to solve this problem ?

Thanks in advance.

True

I see you've tested your code using the Python interpreter and the App Engine production environment. But have you tried running your app on the dev appserver in the GAE Python SDK? Try it and see what errors crop up.

Can you try using version: "1.1.7" (include the quotation marks)?

I did. I developed the whole Application within a local installation of GAE SDK ...

release: "1.8.0"

timestamp: 1367368689
...

Enviroment is Ubuntu 12.10 and Ubuntu 13.04 with raw OS Python installation from repositories... I installed python-imaging to have PIL locally available. All works fine. ... The online-GAE throws this The _imaging C module is not installed-error.

I did ...  I tried ...

version: latest
version: "latest"
version: 1.1.7
version: "1.1.7"

Nothing changed after each variant.

Hey Dennis,

Did you find a solution to this issue?  I'm having the same problem...

[Dennis Hafemann]

Hey Scott,

actually not... The Python-Version on Google App Engine seems to be compiled without necessary libraries ... I guess because of memory-leaking and security issues... I don't know... I tried the hell everthing

To solve my problem I forked PyPNG on GitHub, changed it to make it work with streams, used it as a submodule, worked pretty fine, so that's why I didn't do any further researches ... Take a look on my project, maybe it helps you out to solve your problem.

Hmm that's really weird that there is that limitation.  Thanks for sharing your solution, you've saved me a lot of time where I would've been banging my head against the keyboard!
