"IOError: decoder zip not available" : Ubuntu Python PIL
Solution 1
I just encountered a similar issue caused by having both PIL (installed through the python pip installer) and the python-imaging package installed via apt-get. When I removed the extra version from pip that resolved it for me.
If you installed PIL from source or using pip then you might have the same problem.
When I was building PIL I also discovered that I had to link over the libraries to /usr/lib. That might resolve the not supported messages in your log above.
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
Solution 2
I remember arriving at the exact same solution as Kris did when installing PIL on 64 bit systems.
However nowadays I would recommend using Pillow (pip install pillow) instead of PIL. Pillow is simply a fork of PIL with more frequent releases and less issues like the one you're experiencing.
If you're on Ubuntu I think you need zlib1g-dev and libjpeg-dev installed before installing PIL/Pillow so that you get support for jpeg/png built in.
Solution 3
Even though my PIL was up to date, I resolved this on Ubuntu 12.04 with:
pip uninstall PIL
pip install PIL
Solution 4
This worked Perfectly for me:
apt-get install libjpeg62 libjpeg62-dev zlib1g-dev libfreetype6 libfreetype6-dev
In x86_64:
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
In i386:
ln -s /usr/lib/i386-linux-gnu/libz.so /usr/lib/
ln -s /usr/lib/i386-linux-gnu/libfreetype.so.6 /usr/lib/
ln -s /usr/lib/i386-linux-gnu/libjpeg.so /usr/lib/
pip install -U PIL --allow-external PIL --allow-unverified PIL
pip install -I pillow

I am trying to get the sample heatmap.py running from: http://jjguy.com/heatmap/
#image.py import heatmap import random if __name__ == "__main__": pts = [] for x in range(400): pts.append((random.random(), random.random() )) print "Processing %d points..." % len(pts) hm = heatmap.Heatmap() img = hm.heatmap(pts) img.save("classic.png")
and I get this error:
Processing 400 points... Traceback (most recent call last): File "/home/ec2usr/workspace/image/image.py", line 14, in <module> img.save("classic.png") File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 1437, in save save_handler(self, fp, filename) File "/usr/local/lib/python2.7/dist-packages/PIL/PngImagePlugin.py", line 572, in _save ImageFile._save(im, _idat(fp, chunk), [("zip", (0,0)+im.size, 0, rawmode)]) File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFile.py", line 481, in _save e = Image._getencoder(im.mode, e, a, im.encoderconfig) File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 399, in _getencoder raise IOError("encoder %s not available" % encoder_name) IOError: encoder zip not available
Working off of Eclipse on an Ubuntu 12 (64bit) system, with Python 2.7.
I find libz.so in both /usr/lib and /usr/lib/x86_64-linux-gnu/ just fine. I've tried these solutions already without result:
PIL says it has "support available" but still gives IOError when saving files

I've been pulling my hair out over this for a few days and greatly appreciate anyone's help!

nucleartide over 10 yearsHere to confirm that you need to install dependencies before installing PIL/Pillow, so the installation process performs the proper compilation steps.

ThatAintWorking about 10 yearsThis was the correct answer for me and it works on Ubuntu 12.04 and 14.04 both with python 2.7 and 3.4
