OS X Pillow安装错误

Question

我按照这个说明进行了操作：http://pillow.readthedocs.org/en/latest/installation.html#mac-os-x-installation

$ sudo pip install Pillow

结果出现了错误：

clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]

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

error: command 'cc' failed with exit status 1

在 pip.log 文件中：

请帮帮我！

更新：

我之前安装过PIL。安装后，我尝试了一些复杂的操作来让PIL和libjpeg一起工作。然后我又尝试重新安装PIL。虽然卸载成功了，但安装却失败了。

在使用XCode 5.1的时候，似乎出现了一些问题。我在安装pycrypto的时候也遇到了同样的问题。

可以试试这个：

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