Django Image Uploading Error On Mac Os X

Update (2011-11-18): Ubuntu机器上也出现了一个与此类似的问题，解决方案是执行下面命令后再重装PIL库

sudo apt-get install libjpeg-dev libpng-dev zlib1g-dev liblcms1-dev python-dev

Update (2012-12-22):

There is no /usr/share/libtool/config.sub and /usr/share/libtool/config.guess in my Mac OS 10.8
But we can get them from http://www.gnu.org/software/libtool/news.html.

And if PIL still doesn't work. install brew install libjpeg and brew link jpeg.

Change PIL setup.py like /usr/local/Cellar/jpeg/8d, then built PIL with python setup.py build_ext -i

做项目的时候遇到在Admin Sites下面上传jpg图片报错的问题： Upload a valid image. The file you uploaded was either not an image or a corrupted.

Google了下，发现这是Mac下PIL没有被正确安装的原因

解决方案是先装Apple XCodeTools 再装jpg图片的一个库：libjpeg

cp /usr/share/libtool/config.sub .
cp /usr/share/libtool/config.guess .
./configure –enable-shared
make
sudo mkdir -p /usr/local/include
sudo mkdir -p /usr/local/bin
sudo mkdir -p /usr/local/lib
sudo mkdir -p /usr/local/man/man1
sudo make install

然后重装PIL就ok了

# in setup.py
JPEG_ROOT = "/usr/local/include"
ZLIB_ROOT = "/usr/local/include"
# rebuild and install
python setup.py build_ext -i
# 这一步测试通过才行！
python selftest.py
sudo python setup.py install
