osx python setup.py不会安装xattr-0.6.1应用程序

我不熟悉svn和python，但我真的希望使用比操作系统附带的原始版本更新的xattr版本，它包含更多有用的功能

在OSX 10.5.6上，我在安装xattr-0.6.1时遇到问题

从终端中的本地计算机：

$ svn co http://svn.red-bean.com/bob/xattr/releases/xattr-0.6.1/

这些文件被下载并放置在~/xattr-0.6.1中/

$ cd xattr-0.6.1/
$ sudo python setup.py install

---------------------------------------------------------------------------
This script requires setuptools version 0.6c11 to run (even to display
help).  I will attempt to download it for you (from
http://pypi.python.org/packages/2.5/s/setuptools/), but
you may need to enable firewall access for this script first.
I will start the download in 15 seconds.

(Note: if this machine does not have network access, please obtain the file

   http://pypi.python.org/packages/2.5/s/setuptools/setuptools-0.6c11-py2.5.egg

and place it in this directory before rerunning this script.)

要检查python的版本，请执行以下操作：

$ python -V
Python 2.5.1

它似乎已经安装了python更新

我尝试再次运行xattr安装：

$ sudo python setup.py install

我是否缺少一个重要的基本元素，或者setup.py配置有什么问题，或者我可能忽略了什么？

它需要编译一个C文件，所以它需要

gcc

。Mac用户需要安装更新正如@jathanism提到的，你应该有一张随Mac电脑附带的XCode安装DVD（很可能是3.2版）

例如：

atlas% which gcc
/usr/bin/gcc
atlas% gcc -v
Target: i686-apple-darwin10
..
Thread model: posix
gcc version 4.2.1 (Apple Inc. build 5666) (dot 3)

这个链接是到XCode 4的，你必须购买它。适合您的系统版本的XCode版本捆绑在“可选安装”目录下的安装DVD上。非常感谢您的sirs@samplebias，@jathanism。原来我的10.5紧身衣升级磁盘有Xcode 3.0，其中包括GCC4.0。安装Xcode后，我能够运行setup.py，现在安装了更新版本的xattr.：）很高兴听到你开始跑步了！
