问题
I am getting the:
IOError: decoder zip not available
when I try to draw an image and save to a jpeg in PIL. Any thoughts on how to resolve this? PIL has worked fine for me in the past, when it comes to viewing/uploading images.
回答1:
It likely only needs the zip decoder to save the jpeg. I think I needed to follow these steps in OS X to preview jpegs.
It probably means you need to:
- Download the PIL source.
- Download the zlib library.
- Point the PIL source to the zlib library.
- Build PIL.
回答2:
sudo pip uninstall PIL
sudo pip install pillow
^^ fixed it for me.
Pillow is a fork of PIL that is compatible with pip/setuptools and gets a little better maintenance. I haven't seen any API differences yet.
Edit: There is one notable API difference. PIL exposes Image as a top-level namespace, so you can
import Image # in PIL only
but
from PIL import Image # in pillow or PIL
- Thanks, Leopd!

The more detail installation PIL with zlib library in Ubuntu 64 bit :
http://obroll.com/install-python-pil-python-image-library-on-ubuntu-11-10-oneiric/
For the lazy (credits to @meawoppl for the apt-get):
$ sudo apt-get install libjpeg-dev zlib1g-dev

I encountered this problem on a 64bit ubuntu 13.04 desktop version and here is how I resolved it.
try to reinstall PIL, and pay attention to the output info after you reinstalled:
---------------------------------------------------------------------
PIL 1.1.7 SETUP SUMMARY
--------------------------------------------------------------------
version 1.1.7
platform linux2 2.7.4 (default, Sep 26 2013, 03:20:26)
[GCC 4.7.3]
--------------------------------------------------------------------
*** TKINTER support not available
--- JPEG support available
*** ZLIB (PNG/ZIP) support not available
--- FREETYPE2 support available
*** LITTLECMS support not available
--------------------------------------------------------------------
notice that there is a line :*** ZLIB (PNG/ZIP) support not available,
which means PIL have been built without ZLIB support, and I fixed it by doing this:
first you should have these packages install: libjpeg-dev libfreetype6-dev zlib1g-dev
sudo apt-get install python-dev libjpeg-dev libfreetype6-dev zlib1g-dev
# create these links, if already exists, remove it and re-link it
ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib
ln -s /usr/lib/x86_64-linux-gnu/libfreetype.so /usr/lib
ln -s /usr/lib/x86_64-linux-gnu/libz.so /usr/lib
# reinstall PIL
pip uninstall PIL
pip install PIL
This time, there should be a line --- ZLIB (PNG/ZIP) support available in the output.

I encountered same problem. It seems to me that Pillow and pillow (different case in 'p') are two different packages. So, if you are using Pillow, pip install pillow might not help. Here is my solution:
$ pip uninstall pillow
$ pip uninstall Pillow
$ sudo apt-get install libjpeg-dev zlib1g-dev
$ pip install -I Pillow
First two lines are to remove any pillow or Pillow package.
Third line is to install the two required packages.
Forth is re-install Pillow.
Note, if you are using virtualenv, pip install/uninstall must be run under virtualenv

The way I fixed this on OS X Mavericks was by doing this:
Install brew:
http://brew.sh/
Install pip:
http://www.pip-installer.org/en/latest/installing.html
With those in place, you can do this:
sudo brew install lzlib # installs zlib
pip uninstall PIL
pip install --no-index -f http://dist.plone.org/thirdparty/ -U PIL
After that, it was working fine. For an explanation of the third line, check this answer:

on mac
sudo brew install lzlib # installs zlib
pip uninstall PIL
pip install PIL

I use 64bit ubuntu 14.04LTS desktop version, and I tried Johnny Zhao's answer.
When
exec sudo easy_install PIL
I got an error:
can't find freetype/fterrors.h
and I find freetype2 in /usr/include/
You could solve it by:
sudo ln -s /usr/include/freetype2 /usr/include/freetype
then install will be success
回答9:
The cause may be you've installed Pillow without zlib support.
On CentOS 7:
yum install zlib zlib-devel
pip install Pillow --upgrade
And if you are using for a webapp restart your webserver to apply.

on my case, i just remore python-image, make sure that libz is ready then reinstall PIL, more detail you can see on my post here :

Mac OS X PIL JEPG and PNG issues (same for linux os), this Post help me out of both PNG and JPEG issues with PIL : decoder zip not available and decoder jpeg not available
Make sure JPEG and ZLIB are available, when you install / reinstall PIL :
$ cd Imaging-1.1.7
$ python setup.py build_ext -i
$ python selftest.py
--------------------------------------------------------------------
--- TKINTER support available
--- JPEG support available
--- ZLIB (PNG/ZIP) support available
*** FREETYPE2 support not available
*** LITTLECMS support not available

I tried the version 2.8.0 it works fine me
pip install -Iv Pillow==2.8.0
回答13:
On Ubuntu 18 I have had to install pillow 2.8.1:
pip install Pillow==2.8.1
回答14:
Try:
$ sudo apt-get install python-dev
$ sudo apt-get install libjpeg8-dev
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib
Starting from version 3.0.0 Pillow needs libjpeg. If the issue persists, there might be some package incompatibility. Save some time and try the previous version:
$ pip install Pillow==2.8.1
