Python – PIL decoder jpeg not available on ubuntu x64,

jpegpythonpython-imaging-library

I know that this question looks like a duplicate but I've followed many online instructions on how to properly install PIL and none have worked.

I've tried everything in: Python Image Library fails with message "decoder JPEG not available" – PIL with no success.

When I run sudo pip install pil, worst of all, there is a misleading error. Jpeg, Freetyle, etc support is all listed as available. But when running some python code using PIL, the
notorious IOError of "decoder jpeg not available' comes up.

Even after symlinking into /usr/lib for the .so libjpeg files, nothing has worked.

Any ideas? Thank you.

You can try this:

1. clear PIL packages

rm -rf /usr/lib/python2.7/site-packages/PIL
rm -rf /usr/lib/python2.7/site-packages/PIL.pth

2. install required packages

ubuntu:
apt-get install libjpeg-dev libfreetype6-dev zlib1g-dev libpng12-dev

centos:
yum install zlib zlib-devel
yum install libjpeg libjpeg-devel
yum install freetype freetype-devel

3.download Image and install

wget http://effbot.org/downloads/Imaging-1.1.7.tar.gz
tar xzvf Imaging-1.1.7.tar.gz
cd Imaging-1.1.7
# if the sys is x64, you must also do this: edit the setup.py file and set:
# centOS:
TCL_ROOT = '/usr/lib64'
JPEG_ROOT = '/usr/lib64'
ZLIB_ROOT = '/usr/lib64'
TIFF_ROOT = '/usr/lib64'
FREETYPE_ROOT = '/usr/lib64'
LCMS_ROOT = '/usr/lib64'
# Ubuntu:
TCL_ROOT = '/usr/lib/x86_64-linux-gnu'
JPEG_ROOT = '/usr/lib/x86_64-linux-gnu'
ZLIB_ROOT = '/usr/lib/x86_64-linux-gnu'
TIFF_ROOT = '/usr/lib/x86_64-linux-gnu'
FREETYPE_ROOT = '/usr/lib/x86_64-linux-gnu'
LCMS_ROOT = '/usr/lib/x86_64-linux-gnu'
#then install it use:
python2.7 setup.py install

4. check if it works

# before this command you should run `mv PIL PIL2`

python2.7 selftest.py

If the result is:

--- PIL CORE support ok
--- TKINTER support ok
--- JPEG support ok
--- ZLIB (PNG/ZIP) support ok
--- FREETYPE2 support ok
*** LITTLECMS support not installed
--------------------------------------------------------------------
Running selftest:
--- 57 tests passed.

Congratulation!!

You probably need more packages. Install libjpeg which includes /usr/lib/libjpeg.so* and try again.

On my Fedora (another version), PIL is installed with the python-imaging rpm :

ldd _imaging.so
    linux-gate.so.1 =>  (0x004c6000)
    libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x00a07000)
    libz.so.1 => /lib/libz.so.1 (0x00b91000)
    libpython2.5.so.1.0 => /usr/lib/libpython2.5.so.1.0 (0x00110000)
    libpthread.so.0 => /lib/libpthread.so.0 (0x00ee8000)
    libc.so.6 => /lib/libc.so.6 (0x00260000)
    libdl.so.2 => /lib/libdl.so.2 (0x003c9000)
    libutil.so.1 => /lib/libutil.so.1 (0x00fcd000)
    libm.so.6 => /lib/libm.so.6 (0x00ad1000)
    /lib/ld-linux.so.2 (0x007a1000)

Which means PIL needs libjpeg.so.

libjpeg-dev is required to be able to process jpegs with pillow (or PIL), so you need to install it and then recompile pillow. It also seems that libjpeg8-dev is needed on Ubuntu 14.04

If you're still using PIL then you should really be using pillow these days though, so first pip uninstall PIL before following these instructions to switch, or if you have a good reason for sticking with PIL then replace "pillow" with "PIL" in the below).

On Ubuntu:

# install libjpeg-dev with apt
sudo apt-get install libjpeg-dev
# if you're on Ubuntu 14.04, also install this
sudo apt-get install libjpeg8-dev

# reinstall pillow
pip install --no-cache-dir -I pillow

If that doesn't work, try one of the below, depending on whether you are on 64bit or 32bit Ubuntu.

For Ubuntu x64:

sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib
sudo ln -s /usr/lib/x86_64-linux-gnu/libfreetype.so /usr/lib
sudo ln -s /usr/lib/x86_64-linux-gnu/libz.so /usr/lib

Or for Ubuntu 32bit:

sudo ln -s /usr/lib/i386-linux-gnu/libjpeg.so /usr/lib/
sudo ln -s /usr/lib/i386-linux-gnu/libfreetype.so.6 /usr/lib/
sudo ln -s /usr/lib/i386-linux-gnu/libz.so /usr/lib/

Then reinstall pillow:

pip install --no-cache-dir -I pillow

(Edits to include feedback from comments. Thanks Charles Offenbacher for pointing out this differs for 32bit, and t-mart for suggesting use of --no-cache-dir).
