Django - No module named PIL

I need to use ImageField in my models and PIL seems not to be installed:

>>> from PIL import Image
Traceback (most recent开发者_C百科 call last):
  File "<console>", line 1, in <module>
ImportError: No module named PIL

However I can see python-imaging installed in Synaptic. When I try to easy-install it, I get:

$ sudo easy_install-2.7 PIL

To add a missing option, make sure you have the required
library, and set the corresponding ROOT variable in the
setup.py script.

To check the build, run the selftest.py script.

And this is still not usable. Do I have to do something else to be able to use the ImageField field type ?

Samuele Mattiuzzo gave me the answer:

have you tried with import Image instead of from PIL import Image? sometimes this solves the issue

Also sometimes this may not work:

pip install pil

I know this is an old question already answered, but I found another way to solve it that corrected the problems in my server. The PIL package was installed by easy_install and stored in "/usr/local/lib/python2.6/site-packages/PIL-1.1.7-py2.6-linux-x86_64.egg". Looking on its contents resulted on:

Well. No module PIL to import from. So, I did a dirty trick. Made a folder called PIL and copied all this files inside it.

mkdir PIL
cp * PIL/

So, everything started to work fine. I think this is the problem, depending on the instalation package you use, it will be deployed in a different way. ;)

If your question is "why is the support for JPEG, FREETYPE2 etc, not available?",

PIL installs with the support for the packages that are already present in your system while you install PIL.

For support of JPEG and FREETYPE install following packages:

sudo aptitude install libjpeg libjpeg-dev
sudo aptitude install libfreetype6 libfreetype6-dev

If you have just installed it on OS X Lion and a third party lib cannot from PIL import image, then you can just do a ln -s PIL-OSX... PIL

The problem comes from how package managers setup(.py) PIL:

https://mail.python.org/pipermail/image-sig/2010-August/006480.html

Possible solutions:

• Rename the EGG to "PIL."
• Adjust your code to your installed package (not always possible.)
• Perform a hack like Jayme did (elsewhere on this page.)
• Use a different package for installation.
• Manually configure setup.py for your installation.

"Rename the EGG" is not described elsewhere on this page, so I'll describe it here:

cd /usr/local/lib/python2.6/site-packages/
mv PIL-1.1.7-py2.6-linux-i686.egg PIL

It may be surprising, but this actually works in many situations.
