There is a bug reported for Pillow here, which indicates that libjpeg
and zlib
are now required as of Pillow 3.0.0.
The installation instructions for Pillow on Linux give advice of how to install these packages. Note that not all of the following packages may be missing on your machine (comments suggest that only libjpeg8-dev
is actually missing).
The latest releases of Pillow are available on PyPi as wheels — the new standard packaging mechanism for Python. These prebuilt packages include all neccessary binary dependencies to allow Pillow to run and should be used if you want to install Pillow using PyPi
To use wheels, you need to have a version of pip>=1.4
. If you are using an earlier version (pip --version
) upgrade pip using the following:
pip install --upgrade pip
Once pip
is upgraded, pip install
will use platform-specific wheel files by default if they are available. Use the following command to upgrade Pillow to the latest version available on PyPi:
pip install --upgrade pillow
sudo apt-get install libtiff4-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk
sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk
sudo apt install libjpeg8-dev zlib1g-dev
The Fedora 20 equivalent of libjpeg8-dev
is libjpeg-devel
.
sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel lcms2-devel libwebp-devel tcl-devel tk-devel
On Mac OS X with Homebrew this can be fixed using:
brew install libjpeg zlib
You may also need to force-link zlib using the following:
brew link zlib --force
Update April 2019: In Mojave the above will not work and you need to run the following as taken from this bug report on Pillow
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
Update July 2016: There is no longer a formula for zlib
available in the main repository (Homebrew will prompt you to install lzlib
which is a different library and will not solve this problem).
There is a formula available in the dupes repository. You can either tap this repository, and install as normal:
brew tap homebrew/dupes
brew install zlib
Or you can install zlib
via xcode
instead, as follows:
xcode-select --install

After these are installed the pip installation of Pillow should work normally.
