Problems with Snow Leopard, Django & PIL

问题

I am having some trouble getting Django & PIL work properly since upgrading to Snow Leopard.

I have installed freetype, libjpeg and then PIL, which tells me:

--- TKINTER support ok
--- JPEG support ok
--- ZLIB (PNG/ZIP) support ok
--- FREETYPE2 support ok

but when I try to upload a jpeg through the django admin interface I get:

Upload a valid image. The file you uploaded was either not an image or a corrupted image.

It works fine with PNG files.

Any Ideas?

I had the same experience with Leopard 10.5.x Here is what I did to fix it, (may not work for you).

Go to your PIL working folder (where you unzipped PIL) cd to your build folder cd to your lib.macosx-10.* folder (specific to your os) remove *.so cd back to your PIL build folder (I logged in as su for this, but you can sudo these if you like)
python setup.py clean
python setup.py build
python setup.py install

This rebuilds PIL clean. The reason your jpeg reports ok, is that it just looks for the existence of the jpeg lib files, but not the dependency that happens from a clean build and install of PIL.

Hope this solves your problem, mine was more likely related to the order of installation but maybe it will help...

As a follow up to Ken's response, I had the same problem with Snow Leopard 10.6.x which was caused by installing PIL before libjpeg. After installing libjpeg, I reinstalled PIL by doing the following.
