I tried to use PIL to do some JPEG work in my django app with PIL but I'm getting this IOError.. not sure what to do.
""decoder jpeg not available""
Am I missing the JPEG decoder from my server? If so, how do I fix it?
You need to install jpeg library first and reinstall your PIL. For example, I'm using CentOS, to install libjpeg, I run
sudo yum install -y libjpeg-devel
It depends on what kind of linux you are using. And here you have to remove the old PIL
rm -rf /usr/lib/python2.6/site-packages/PIL-1.1.7-py2.6-linux-x86_64.egg/
Then install the PIL
sudo easy_install PIL
I have found this answer from author "edward"
On Ubuntu precise, PIL doesn't find the jpeg library files, even once they are installed. The easiest way to fix this is to make a symlink after you have installed the jpeg dev package. So, I needed an extra step:
for x64 OS
pip uninstall PIL sudo apt-get install libjpeg8-dev sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib pip install PIL
for x32 OS
pip uninstall PIL sudo apt-get install libjpeg8-dev sudo ln -s /usr/lib/i386-linux-gnu/libjpeg.so /usr/lib pip install PIL
I confirm that this is working for me on Ubuntu Linux 12.04.
If you are a Mac user - you need to install Xcode and Command Line Tools. Read how to do this
