Install Pillow with pip on OS X Mavericks 10.9.1
I recently ran into an issue on Mavericks where installing the python package Pillow would not install correctly and error out on my, referencing a clang error that I was in no mood to debug.
clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]
I Googled a solution for about 20 minutes until I found this: before running
pip install, run this
export CFLAGS=-Qunused-arguments export CPPFLAGS=-Qunused-arguments
Update: I’ve noticed as of version 18.104.22.168.1.1396320587 of XCode Command Line Tools, the above temp-fix doesn’t seem to work is you’re using
sudo to install a package. To use
sudo, make sure you append the
sudo -E pip install PACKAGE
