easy_install lxml在os x 10.5上的困难

Question

我正在尝试在我的计算机上安装lxml，但是遇到了问题。有人能帮上忙吗？当我尝试执行'easy_install lxml‘时，我已经提供了我得到的终端输出。我运行的是MacOSX10.5和Python版本2.7.2。谢谢！：

我不能仅仅通过查看错误来告诉你根本原因，但有几个简单的事情你可以先试一下：

• 以超级用户(sudo easy_install lxml)身份运行安装程序。
• 尝试使用pip进行安装。我很幸运地使用pip在OSX 10.6和10.7上安装了lxml。如果你还没有pip，那就执行sudo easy_install pip。然后做sudo pip install lxml.

如果这不起作用，请告诉我们。

编辑:我相信easy_install和pip都使用相同的包repos，但值得一试。
