Installing Pillow, getting -Wunused-command-line-argument-hard-error-in-future

问题

I cannot get pillow installed.

(env)noah:cupalensic2 broinjc$ which cc
/usr/bin/cc
(env)noah:cupalensic2 broinjc$ cc --version
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.1.0
Thread model: posix

I ran pip install mezzanine and when it got to satisfying pillow it screwed up...

clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

Any idea what might be going on here?

回答1:

This is a known issue with OSX and recent Xcode upgrade.

Instructions how to avoid the issue are here:

Ansible Installation -clang: error: unknown argument: '-mno-fused-madd'

This should do the trick::

  ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install Pillow
