如何在Windows上安装LXML

Question

我正在尝试lmxl使用Python 3.4将其安装在Windows 8.1笔记本电脑上，但失败了。

首先，我尝试了简单明了的解决方案：pip install lxml。但是，这没有用。它是这样说的：

所以然后我看了一个很棒的有用的东西，叫做 互联网 ，很多人都需要libxml2和错误libxlst。他们推荐了一个叫Christoph
Gohlke的页面，其中他为一堆软件包提供了一些二进制工具。您可以在这里找到它（到lxml部分的快速链接）。

因此，在我放弃尝试为点子找到libxml2和libxslt之后，我决定去那里，发现 了
很多下载内容。我知道我需要一个64位的，但是我不知道cp我需要哪个。

因此，为我提供该pip方法的解决方案或Gohlke指数方法的答案都将是不错的。

Answer 1

首先，按照注释，我下载了lxml-3.4.2-cp34-none-win_amd64.whl文件并尝试使用来打开它pip install，但它只是告诉我它在我的系统上不是有效的wheel文件。

然后，我下载了win_32文件并成功了！也许是因为我拥有Intel处理器，毫不奇怪，AMD64仅适用于AMD处理器。
