在 Mountain Lion 更新之前，它就像一个魅力一样工作。

更新后它坏了，我无法重新启动环境。

有人知道如何解决这个问题吗？

错误在下方以粗体显示。

更新:

按照提示，我添加了

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

但是它把错误改成了

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

我只是修改了这个目录以允许写入并且它起作用了:) 这是由于混用了 macports、easy_install 和 pip……真丢人。

最佳答案

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 的构建方式所致。在运行 pip 之前尝试添加这些环境变量值:

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

参见 clang error: unknown argument: '-mno-fused-madd' (python package installation failure)获取更多信息。

更新 [2014-05-16]:正如预期的那样，Apple 已通过 OS X 10.9.3 中更新的系统 Python(2.7、2.6 和 2.5)解决了这个问题，因此解决方法是 no使用最新的 Mavericks 和 Xcode 5.1+ 时不再需要。但是，到目前为止，如果您在那里使用 Xcode 5.1+，OS X 10.8.x(Mountain Lion，当前为 10.8.5)仍然需要解决方法。

关于python - 无法在 Mac Mavericks 上安装 python mysql 库，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22413050/
