Python Image Library fails with message decoder JPEG not available - PIL

Question

PIL does support JPEG in my system   Whenever I do an upload  my code is failing with   File  PIL Image py   line 375  in  getdecoder     raise IOError  decoder  s not available    decoder name  IOError  decoder jpeg not available   How can I resolve this

Same problem here  JPEG support available but still got IOError  decoder encoder jpeg not available  except I use Pillow and not PIL   I tried all of the above and more  but after many hours I realized that using sudo pip install does not work as I expected  in combination with virtualenv  Silly me   Using sudo effectively launches the command in a new shell  my understanding of this may not be entirely correct  where the virtualenv is not activated  meaning that the packages will be installed in the global environment instead   This messed things up  I think I had 2 different installations of Pillow    I cleaned things up  changed user to root and reinstalled in the virtualenv and now it works  Hopefully this will help someone

Rolo s answer is excellent  however I had to reinstall Pillow by bypassing pip cache  introduced with pip 7  otherwise it won t get properly recompiled    The command is   pip install -I --no-cache-dir -v Pillow   and you can see if Pillow has been properly configured by reading in the logs this   PIL SETUP SUMMARY     --------------------------------------------------------------------     version      Pillow 2 8 2     platform     linux 3 4 3  default  May 25 2015  15 44 26                    GCC 4 8 2      --------------------------------------------------------------------         TKINTER support not available     --- JPEG support available         OPENJPEG  JPEG2000  support not available     --- ZLIB  PNG ZIP  support available     --- LIBTIFF support available     --- FREETYPE2 support available         LITTLECMS2 support not available         WEBP support not available         WEBPMUX support not available     --------------------------------------------------------------------   as you can see the support for jpg  tiff and so on is enabled  because I previously installed the required libraries via apt  libjpeg-dev libpng12-dev libfreetype6-dev libtiff-dev

This question was posted quite a while ago and most of the answers are quite old too  So when I spent hours trying to figure this out  nothing worked  and I tried all suggestions in this post   I was still getting the standard JPEG errors when trying to upload a JPG in my Django avatar form   raise IOError  decoder  s not available    decoder name  OSError  decoder jpeg not available   Then I checked the repository for Ubuntu 12 04 and noticed some extra packages for libjpeg  I installed these and my problem was solved   sudo apt-get install libjpeg62 libjpeg62-dev   Installing these removed libjpeg-dev  libjpeg-turbo8-dev  and libjpeg8-dev   Hope this helps someone in the year 2015 and beyond   Cheers

On Fedora 17 I had to install libjpeg-devel and afterwards reinstall PIL   sudo yum install --assumeyes libjpeg-devel sudo pip-python install --upgrade PIL

For those on OSX  I used the following binary to get libpng and libjpeg installed systemwide   libpng  amp  libjpeg for OSX  Because I already had PIL installed  via pip on a virtualenv   I ran   pip uninstall PIL pip install PIL --upgrade   This resolved the decoder JPEG not available error for me   UPDATE  4 24 14    Newer versions of pip require additional flags to download libraries  including PIL  from external sources  Try the following   pip install PIL --allow-external PIL --allow-unverified PIL   See the following answer for additional info  pip install PIL dont install into virtualenv  UPDATE 2   If on OSX Mavericks  you ll want to set the ARCHFLAGS flag as  RicardoGonzales comments below    ARCHFLAGS -Wno-error unused-command-line-argument-hard-error-in-future pip install PIL --allow-external PIL --allow-unverified PIL

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

I was already using Pillow and got the same error  Tried installing libjpeg or libjpeg-dev as suggested by others but was told that a  newer  version was already installed   In the end all it took was reinstalling Pillow   sudo pip uninstall Pillow sudo pip install Pillow

For Fedora  Install  pre-requisite  sudo dnf install make automake gcc gcc-c   kernel-devel rpm-build libjpeg-devel zlib-devel python-devel    Now install Pillow  sudo pip install pillow  Note - For libjpeg and zlib we are installing libjpeg-devel and zlib-devel packages in Fedora CentOS Red Hat

The followed works on ubuntu 12 04   pip uninstall PIL apt-get install libjpeg-dev apt-get install libfreetype6-dev apt-get install zlib1g-dev apt-get install libpng12-dev pip install PIL --upgrade   when your see  -- JPEG support avaliable  that means it works   But  if it still doesn t work when your edit your jpeg image  check the python path    my python path missed  usr local lib python2 7 dist-packages PIL-1 1 7-py2 7-linux-x86 64 egg   so I edit the    bashrc add the following code to this file   Edit  export PYTHONPATH  PYTHONPATH  usr local lib python2 7 dist-packages PIL-1 1 7-py2 7-linux-x86 64 egg   then  finally  it works

apt-get install libjpeg-dev apt-get install libfreetype6-dev apt-get install zlib1g-dev apt-get install libpng12-dev   Install these and be sure to install PIL with pip because I compiled it from source and for some reason it didn t work

User · Answer

This is the only way that worked for me  Installing packages and reinstalling PIL didn t work   On ubuntu  install the required package   sudo apt-get install libjpeg-dev    you may also want to install libfreetype6 libfreetype6-dev zlib1g-dev to enable other decoders    Then replace PIL with pillow   pip uninstall PIL pip install pillow
