Issues caused by Python Imaging Library on Ubuntu

[sdia]

I was trying to install a new app from openerp dashboard when I had the following error.
The problem is caused by the Python Imaging Library (PIL).
I suggest the replacement of python-pil by python-pillow , a fork, alternative re-packaging of PIL.

My plateform
    * ubuntu 13.04
    * python 2.7 (with virtualenv)

The error:

Actually just changing 'PIL' to 'Pillow' in setup.py made it ! Indeed the code base is already ready to use Pillow

Hello Sdia,

Please let me know that, which app you were trying to install ? I tried same but I am not getting any issue with this. Its working fine at my end.

Hi Christian,

I was trying to install CRM. As I mentionned earlier my platform is Ubuntu 13.04 + Python2.7 virtualenv.
The solution I have mentionned works for me. Since in the Python community Pillow is known to be better than PIL I think it is a good idea to get rid of PIL. I have checked openerp source code and it is Pillow compatible.

Regards,
Seydou.
