无法在Windows上安装lxml，发生致命错误C1083:无法打开包含文件:'libxml/xmlversion.h' [英] Cannot install lxml on windows, fatal error C1083: Cannot open include file: 'libxml/xmlversion.h'

问题描述

Python菜鸟，请多多包涵.我从www.python.org使用了适用于v3.5.1的python安装程序.我的目的是使用Scrapy运行一些脚本.

Python noob, please bear with me. I used python installer for v3.5.1 from www.python.org. My intent was to use Scrapy to run some scripts.

pip install scrapy失败，easy_install scrapy等也失败了.我将错误跟踪到lxml的错误安装.这是错误日志.我什至尝试过easy_installing libxml2，我不确定如何继续.

pip install scrapy failed, as did easy_install scrapy and others. I traced the error to a faulty install of lxml. Here is the error log. I've even tried easy_installing libxml2, I'm not sure how to proceed.

Building lxml version 3.5.0.

推荐答案

尽管使用WinPython 64位2.7.3.1.，我也遇到了同样的问题.

I had the same problem, albeit using WinPython 64bit 2.7.3.1.

我使用可在此处找到的预编译安装程序解决了该问题: https://pypi.python.org/pypi/lxml/3.3.3#downloads

I solved it using the precompiled installer which can be found here: https://pypi.python.org/pypi/lxml/3.3.3#downloads

通过运行.exe直接安装软件包失败，因为安装程序找不到我的python安装(尽管已注册). 但是，我随后成功地使用了WinPython控制面板来安装该软件包！

Directly installing the package by running the .exe failed, because the installer could not find my python installation (altough it is registered). However, I then successfully used the WinPython Control Panel to install the package!

在此之前，我尝试了在stackoverflow上发现的各种方法，包括安装一些Visual C ++(Python)编译器，但没有一个起作用.

edit: before that, I tried various things which I found on stackoverflow, including installing some Visual C++ (Python) compilers but none of that worked.
