解决方案
clang通过在编译之前设置以下环境变量，不会将此错误提升为：
export CFLAGS = -Qunused-arguments
export CPPFLAGS = -Qunused-arguments
然后 pip install psycopg2 应该可以工作。
当尝试 pip install lxml 时， >
编辑：如果您安装为超级用户（这可能是如果你试图附加到 /Library/Python/2.7/site-packages ，原生的苹果工厂安装的Python发行版附带的OS X，而不是一些其他Python分发，你随后安装自己），那么你将需要做，如@Thijs Kuipers
sudo -E pip install psycopg2
或等价物，对于任何其他程序包名称，您可以替换 psycopg2 。
UPDATE [2014-05-16]：Apple已经修复了 OS X 10.9.3 所以当使用最新的小牛和 Xcode 5.1 + 时不再需要解决方法。但是，现在，如果你使用 Xcode，则。 OS X 10.8.x （Mountain Lion，目前为10.8.5）仍然需要解决方法： 5.1 +
I get the following error when attempting to install psycopg2 via pip on Mavericks 10.9:
clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]
Not sure how to proceed and have searched here and elsewhere for this particular error. Any help is much appreciated!

解决方案
You can tell clang to not raise this as an error by setting the following environment variables prior compilation:
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
Then pip install psycopg2should work.
I had the same when trying to pip install lxml.
Edit: if you are installing as superuser (which will likely be the case if you are trying to append to /Library/Python/2.7/site-packages, the native Apple factory-installed Python distribution which ships with OS X, rather than to some other Python distribution which you have subsequently installed yourself), then you will need to do, as described by @Thijs Kuipers in comments below:
sudo -E pip install psycopg2
or the equivalent, for whatever other package name you may be substituting in place of psycopg2.
UPDATE [2014-05-16]: Apple has fixed this problem with updated system Pythons (2.7, 2.6, and 2.5) in OS X 10.9.3 so the workaround is no longer necessary when using the latest Mavericks and Xcode 5.1+. However, as of now, the workaround is still required for OS X 10.8.x (Mountain Lion, currently 10.8.5) if you are using Xcode 5.1+ there.
