我正试图用Python 3.4在我的Windows 8.1笔记本电脑上安装lmxl，但失败惨重.
首先，我try 了简单而明显的解决方案:pip install lxml.然而，这并没有奏效.上面说:

然后我看了一个叫做The Internet的伟大而有用的东西，很多人都有同样的错误，需要libxml2和libxlst.他们推荐一个叫Christoph Gohlke's page的人，他在那里为一堆软件包提供某种二进制内容.你可以找到here(quicklink to the lxml part).
所以在我放弃为pip寻找libxml2和libxslt之后，我决定go 那里，找到了an absolute ton个下载.我知道我需要一个64位的，但我不知道我需要哪个"cp".
所以，给我一个关于pip法或Gohlke指数法的解决方案会很好.
