我试图用Python 3.4在我的Windows 8.1笔记本电脑上安装lmxl ，并且失败了。
首先，我尝试了简单明了的解决scheme： pip install lxml 。 但是，这不起作用。 这就是它说的：

那么我看了这个叫做互联网这个伟大而有用的东西，很多人都有需要libxml2和libxlst错误。 他们推荐一个名叫Christoph Gohlke的页面，他为一堆软件包提供了一些二进制的东西。 你可以在这里find它（快速链接到lxml部分 ）。
所以在我放弃尝试为pipfindlibxml2和libxslt后，我决定去那里，发现绝对的下载量。 我知道我需要一个64位的，但我不知道我需要哪个“ cp ”。
所以给我一个解决方法或Gohlke指数方法的答案会很好。
或者你也可以去Christoph的Gohlke的Python页面 ，然后下载正确的lxml文件。 （通常，因为我使用python 3.4，我有一个窗口，我下载了lxml-3.4.4-cp34-none-win32.whl）
转到它所在的文件夹。点击背景（所以没有选择任何东西），然后左移+右键同时点击打开的命令窗口。 然后键入C：/ Python34 / Scripts / pip install“您正在下载的文件的名称.whl”
在这种情况下，它将是C：/ Python34 / Scripts / pip install“lxml-3.4.4-cp34-none-win32.whl”
现在点击进入。 这对我很好，输入报价后，你也可以按tab，它应该填写正确的一个给你。
首先，在下面的评论中，我下载了lxml-3.4.2-cp34-none-win_amd64.whl文件，并尝试用pip install来打开它，但是它只是告诉我这不是我的系统上的有效轮盘文件，或者一些东西。
然后，我下载了win_32文件，它工作！ 也许这是因为我有一个英特尔处理器，AMD64毫无疑问只适用于AMD处理器。
这些说明适用于使用Python3.4的Windows7或Windows8 。
但是 ，随着python的发布和其他各种先决条件的变化/演变，它们应该可以用于各种版本：
C:\python34\的默认路径 PATH环境变量中，将C:\python33\和C:\python34\scripts文件夹添加到系统路径。 c:\openssl-win32\bin （或类似的）目录添加到PATH ，就像上面添加C:\python34和C:\python34\scripts 。 get-pip.py应该为你安装Setuptools），但是，以防万一…
ez_setup.py并保存在C:\python34\scripts C:\python34\scripts> python ez_setup.py get-pip.py并保存在C:\python34\scripts C:\python34\scripts> python get-pip.py LXML 3.4.4 ，以获得您的Windows和PC体系结构的版本 我最近也遇到这个问题。 pip不能在.whl文件上工作。 而不是解决这个问题，我通过.exe文件安装它。 你可以从这里下载。请选择你的python的正确版本。 希望这可以帮到你。
