Python 在os x 10.5上轻松安装lxml

我正在尝试在我的计算机上安装lxml，但遇到了困难。有人能帮忙吗？我已经提供了当我尝试执行“easy_install lxml”时得到的终端输出。我正在运行MacOSX10.5和Python版本2.7.2。谢谢

我无法通过查看错误来告诉您根本原因，但有两件简单的事情您可以先尝试：

• 如果尚未安装，请以超级用户身份运行安装（

  sudo easy\u install lxml

  ）
• 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，这是值得的。如果您还没有pip，只需执行

  sudo easy\u安装pip

  。然后执行

  sudopip安装lxml

如果不起作用，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。

只是一个猜测，但从错误来看，它似乎找不到libxslt。您可以将其安装在非标准位置（它正在

/usr/lib

中查找），在这种情况下，可能会有一个命令行选项来告诉安装程序在哪里查找。否则，您可能必须在

/usr/lib

中安装libxslt，也许这一行特别指出了问题的根源？gcc-fno严格别名-Wno long double-no cpp precomp-mno fused madd-fno common-dynamic-DNDEBUG-g-Os-Wall-Wstrict原型-DMACOSX-I/usr/include/ffi-DENABLE_DTRACE-arch i386-arch ppc-pipe-I/usr/include/libxml2-I/System/Library/Frameworks/Python.framework/Versions/2.5/include/python2.5-c src/lxml/lxml.etree.c-o build/temp.macosx-10.5-i386-2.5/src/lxml/lxml.etree.o-w-flat_命名空间src/lxml/lxml.etree.c:276:31：错误：libxml/schematron.h:没有这样的文件或目录hmm，您可能有旧的/不匹配的libxml2版本。如果您想避免手动修复带来的麻烦，可以尝试针对lxml的macports包<代码>端口搜索lxml以查看可用版本。
