Question

在Mountain Lion更新之前它就像一个魅力。

更新后它被破坏了，我再也无法恢复环境了。

有人知道如何解决这个问题吗？

错误以粗体显示，如下所示。

更新：

根据建议，我已添加

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

但它将错误更改为

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

我只是chmoded这个目录允许写，它工作:) 这是因为混合macports，easy_install和pip ...羞辱我。

Answer 1

问题是由于Xcode 5.1中引入的更改以及Apple提供的系统Python 2.7的构建方式。尝试在运行pip之前添加这些环境变量值：

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

有关详细信息，请参阅clang error: unknown argument: '-mno-fused-madd' (python package installation failure)。

更新[2014-05-16]：正如预期的那样，Apple已经使用OS X 10.9.3中更新的系统Pythons（2.7,2.6和2.5）解决了这个问题，因此在使用最新的Mavericks时不再需要解决方法和Xcode 5.1+。但是，截至目前，如果您在OS X 10.8.x使用Xcode 5.1+，则{{1}}（Mountain Lion，目前为10.8.5）仍需要解决方法。

Answer 2

以Ned的答案为基础：

由于我不想使用sudo来安装软件包（我正在使用虚拟环境）或影响我的golbal环境，我将这两个变量添加到{{1>的单一执行 }}：

pip install

无法在Mac Mavericks上安装python mysql库
