mac上安装PIL
在写图片上传的时候,碰到PIL不能处理JPG图片,出现异常IOError: decoder jpeg not available
The Python Imaging Library
,
PIL, is a very useful addition to your Python installation if you need
to manipulate pictures. Django uses it to validate upload images for
example.
On a Mac you do need to install libjpegbeforehand.
Install libjpeg:
[*] Get the source: http://www.ijg.org/files/jpegsrc.v6b.tar.gz
[*] Extract the archive.
[*] Move inside the source directory and execute the following commands:
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
Install PIL:
[*] Get PIL at: http://effbot.org/downloads/Imaging-1.1.6.tar.gz
[*] Extract the archive.
[*] Move inside the source directory
[*] Change the following values in setup.py from the default Noneto:
JPEG_ROOT = "/usr/local/include"
ZLIB_ROOT = "/usr/local/include"
[*] Check if everything is well configured:
python setup.py build_ext -i
python selftest.py
[*] If no errors are found and the required libraries are installed (like JPEG support), install PIL:
sudo python setup.py install
And that's it, I've tried this on Mac OS Leopard, and it works fine, let me know how it went for you.
