我想安装pandas以便在Python中使用
我有最新版本的xcode和命令行工具，pip，easy_install，但安装这个一直给我以下错误，任何人都可以帮忙吗？
sudo easy_install pandas

正如评论中所指出的，这是一个现在常见的问题，这是由Xcode 5.1的变化和Apple为系统Python 2.7选择构建选项引起的。您可以通过删除建议的here的违规选项来解决此问题。如果您需要使用sudo（如果您使用系统提供的easy_install，则可能使用它），您还需要确保在sudo环境中定义变量。一种方法是：
sudo bash
umask 022
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
/usr/bin/easy_install pandas
exit
还有其他选择不需要使用sudo或使用virtualenv。
更新[2014-05-16]：正如预期的那样，Apple已经在pip install --user pandas中使用更新的系统Pythons（2.7,2.6和2.5）修复了这个问题，因此在使用最新的Mavericks和OS X 10.9.3时不再需要解决方法。但是，截至目前，如果您在那里使用Xcode 5.1+，OS X 10.8.x（Mountain Lion，目前为10.8.5）仍需要解决方法。
