How to install libjpeg on OSX?

Question

libjpeg or libjpeg-turbo are requirements for installing Pillow, which is a new requirement for storing images on django. So I need to install Pillow but that won't work until I get jpeg support which comes by way of packages called libjpeg or libjpeg-turbo. I hope that is the case, at least.

This dependency is not an issue on the dev server, but I need to do some work locally, (Macbook Pro OSX 10.11.5). Haven't been able to do it yet or find a solution to install yet for OSX. I was hoping I would find something in pip or conda but there is nothing for OSX. I have seen there are various normal ways to install on Linux.

Don't know why I didn't think of homebrew, which I also have already. Thanks a lot! – jeffery_the_wind Jul 12 '16 at 14:20
This does not work anymore, the library can not be found. – Charklewis Nov 16 '20 at 06:01
If I run `brew install libjpeg` I get the same result as with `brew install jpeg` so maybe they renamed it, but it still works for me. – mirosval Dec 02 '20 at 12:11

For libjpeg-turbo

 brew install jpeg-turbo

Then it'll give you instructions on how to add it to your library load path (so that it doesn't conflict with libjpeg, it isn't in the standard paths).

Fresh install of Big Sur (macOS 11.0.1) and Homebrew, then :

brew install jpeg

Then installed XCode command line tools (required because of zlib) via

xcode-select --install

Then in zsh for tools to find headers :

export CPATH=`xcrun --show-sdk-path`/usr/include
export LDFLAGS="-L//Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include"
export CPPFLAGS="-I//Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include"

Lastly in a virtual environment (Python 3.8) :

pip install setuptools, wheel, Pillow
