发现 OS X 10.10 使用 pip 或者 setuptools 的一个坑

[kqz901002]

如果package需要调用clang就会出错。

我的解决方案就是 copy 一个副本到安装目录

我也遇到了… 我都是下载安装包然后 ln 一份 Python.Framework 到目录……

LZ是OS X？Xcode到5.1之后才出现的这个问题，原因是Python包里有些比较特殊的编译参数，新的编译器不认识了。。。

可以在 pip install 之前加上 ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future 忽略这个报错

[hongqn]

原因是 python configure.ac 里的一个 bug
