- Building lxml for Python 2.7 on Windows
- "@ziyuang This would mean you use Python 3.3 which uses Microsoft Visual Studio 2010. If that's the case then the answer is yes, you should install this version."

Facts
事实
- Windows x86 (32-bit)
- Installed both Visual Studio C++ 2008 (from here) Express and Visual Studio C++ 2010 (from here)
- Python 3.4.1 (apparently compiled with newer versionthan Visual Studio 2008)
- I use pip (or pip3.4.exe; builtin to Python 3.4) to
pip install lxml - distutils uses Visual Studio C++ 2010 Express to compile
- Windows x86（32 位）
- 安装了 Visual Studio C++ 2008（从这里）Express 和 Visual Studio C++ 2010（从这里）
- Python 3.4.1（显然是用比 Visual Studio 2008更新的版本编译的）
- 我使用 pip（或 pip3.4.exe；内置于 Python 3.4）来
pip install lxml - distutils 使用 Visual Studio C++ 2010 Express 编译

Update 10/16/2019
2019 年 10 月 16 日更新
As commenter says, the executable links are no longer available
正如评论者所说，可执行链接不再可用
- This archived version(from 2014; executable links don't work) shows the old links
- As commenter says; the sitecurrently has
whl(wheel) files for thelxmllibrary; you can usepipto install fromwhlfiles - Or check out this set of linksto executable files on
pypi.org; the executables only range from 2.6, 2.7, 3.2, 3.3, and 3.4
- 此存档版本（从 2014 年开始；可执行链接不起作用）显示旧链接
- 正如评论者所说；该站点当前具有库的
whl（轮）文件lxml；您可以使用pip从whl文件安装 - 或者查看这组指向可执行文件的链接
pypi.org；可执行文件的范围只有 2.6、2.7、3.2、3.3 和 3.4
Looks like Chris doesprovide a direct exe here:
看起来 Chris确实在这里提供了一个直接的 exe：

Thanks, Chris! Any ideas why I cannot compile using pip?
谢谢，克里斯！任何想法为什么我不能使用 pip 编译？

I also got this problem, but the workarounds provided above are not work for me as well.
我也遇到了这个问题，但上面提供的解决方法对我也不起作用。
Here is my system configuration:
这是我的系统配置：
- Win7 64bit
- python3.3
- visual studio 2013
- Win7 64位
- 蟒蛇3.3
- 视觉工作室 2013
I tried to use the method in the first link in the Related questions, but it's fail. This method is to create a system variable for vs2010 use, and the variable is actually copy from my original configuration in visual studio 2013.
我尝试在相关问题的第一个链接中使用该方法，但失败了。这个方法是创建一个vs2010使用的系统变量，这个变量实际上是从我在visual studio 2013的原始配置复制过来的。
However, the command line prompted error with "libxml/xmlversion.h" no suck file or directory
但是，命令行提示错误“libxml/xmlversion.h”没有suck文件或目录
Then I further searched it on the internet and got a method which works in my case.
然后我在互联网上进一步搜索它并获得了一种适用于我的情况的方法。
downloading the precompiled lxml plugin
Precompiled lxml 3.5: https://pypi.python.org/pypi/lxml/3.3.5#downloads
if your system is 64bit, then you can get a unofficial version for x64 at here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml(this is what i use)
installing with command in command line easy_install lxml-3.2.1.win32-py3.3.?exe
Reference: https://pytools.codeplex.com/workitem/1520
下载预编译的 lxml 插件
预编译的 lxml 3.5：https: //pypi.python.org/pypi/lxml/3.3.5#downloads
如果您的系统是 64 位，那么您可以在此处获得 x64 的非官方版本：http: //www.lfd.uci.edu/~gohlke/pythonlibs/#lxml（这是我使用的）
在命令行中使用命令安装easy_install lxml-3.2.1.win32-py3.3.?exe

The short version is: You need to have the C library libxml2(and also libxslt2) before you can build lxml.
简短的版本是：你需要有C库libxml2（也libxslt2），然后才能建立lxml。
As the lxmlinstallation docssay:
正如lxml安装文档所说：
Unless you are using a static binary distribution (e.g. from a Windows binary installer), you need to install
libxml2andlibxslt, in particular:
libxml22.6.21 or later. It can be found here: http://xmlsoft.org/downloads.html
- We recommend `libxml2 2.7.8 or a later version.
- If you want to use XPath, do not use
libxml22.6.27.- If you want to use the feed parser interface, especially when parsing from unicode strings, do not use
libxml22.7.4 through 2.7.6.
libxslt1.1.15 or later. It can be found here: http://xmlsoft.org/XSLT/downloads.html
- We recommend
libxslt1.1.26 or later.
除非您使用的是静态二进制分发版（例如来自 Windows 二进制安装程序），否则您需要安装
libxml2和libxslt，特别是：
libxml22.6.21 或更高版本。可以在这里找到：http: //xmlsoft.org/downloads.html
- 我们推荐`libxml2 2.7.8 或更高版本。
- 如果要使用 XPath，请不要使用
libxml22.6.27。- 如果要使用提要解析器接口，尤其是从 unicode 字符串解析时，请不要使用
libxml22.7.4 到 2.7.6。
libxslt1.1.15 或更高版本。可以在这里找到：http: //xmlsoft.org/XSLT/downloads.html
- 我们推荐
libxslt1.1.26 或更高版本。
The build from source docssimilarly start off with:
To build lxml from source, you need libxml2 and libxslt properly installed, including the header files.
要从源代码构建 lxml，您需要正确安装 libxml2 和 libxslt，包括头文件。
Windows (unlike most other platforms) doesn't come with these libraries. You don't mention anything in your "Facts" about having them.
Windows（与大多数其他平台不同）没有这些库。您没有在“事实”中提及有关拥有它们的任何内容。
And the error message that you showed is:
您显示的错误消息是：
C:\Users\NATHAN~1\AppData\Local\Temp\pip_build_nathanielanderson\lxml\src\lxml\includes\etree_defs.h(9) :
fatal error C1083: Cannot open include file: 'libxml/xmlversion.h':
No such file or directory
That 'libxml/xmlversion.h'that it can't find is part of libxml2.
这'libxml/xmlversion.h'是它无法找到是的一部分libxml2。
It's also worth noting that the same installation docs explicitly say:
还值得注意的是，相同的安装文档明确指出：
consider using the binary builds from PyPI or the unofficial Windows binaries that Christoph Gohlke generously provides.
考虑使用来自 PyPI 的二进制版本或 Christoph Gohlke 慷慨提供的非官方 Windows 二进制文件。
So, the fact that you thought Christoph Gohlke didn't provide binaries for lxmlimplies that you hadn't found these docs.
因此，您认为 Christoph Gohlke 没有提供二进制文件的事实lxml意味着您没有找到这些文档。
So, it's possible that you did install libxml2, but not in a way that lxml2's setup script can find it. But all the evidence implies it's a lot more likely that you just don't have it.
因此，您可能确实安装了libxml2，但不是lxml2安装脚本可以找到的方式。但所有的证据都表明，你根本没有它的可能性要大得多。
