Cannot install python mysql library on Mac Mavericks

Question

It worked like a charm before upgrading from Mountain Lion.

After the update, it is broken, and I can not restore the environment again.

Does anyone know how to fix this?

The error is highlighted in bold.

UPDATE:

Like I said, I added

export CFLAGS = -Qunused-arguments export CPPFLAGS = -Qunused-arguments

But he changed the error to

 error: /Library/Python/2.7/site-packages/_mysql.so: Permission denied 

I just chmoded this directory to write and it worked :) This is due to mixing macports, easy_install and pip ... shame on me.

Answer 1

The problem is related to changes made in Xcode 5.1 and because of how the Apple Python 2.7 system is created. Try adding these environment variable values ​​before starting pip :

 export CFLAGS=-Qunused-arguments export CPPFLAGS=-Qunused-arguments 

See clang error: unknown argument: '-mno-fused-madd' (python package installation failed) for more information.

UPDATE [2014-05-16]: As expected, Apple fixed this problem with the updated Pythons system (2.7, 2.6, and 2.5) in OS X 10.9.3 , so the workaround is no longer needed when using the latest Mavericks and Xcode 5.1+ . However, for now, a workaround is still needed for OS X 10.8.x (Mountain Lion, currently 10.8.5) if you are using Xcode 5.1+ .

Answer 2

Based on Ned's answer:

Since I don’t want to use sudo to install packages (I use virtual environments) or affect my golbal environment, I added two variables to the single pip install run:

CFLAGS=-Qunused-arguments CPPFLAGS=-Qunused-arguments pip install -r requirements.txt
