[英]Cannot install lxml on windows, fatal error C1083: Cannot open include file: 'libxml/xmlversion.h'
Python noob, please bear with me. Python菜鸟,请多多包涵。 I used python installer for v3.5.1 from www.python.org.
我使用来自 www.python.org 的 v3.5.1 的 python 安装程序。 My intent was to use Scrapy to run some scripts.
我的意图是使用 Scrapy 来运行一些脚本。
pip install scrapy failed, as did easy_install scrapy and others. pip install scrapy 失败,easy_install scrapy 和其他人也是如此。 I traced the error to a faulty install of lxml.
我将错误追溯到 lxml 的错误安装。 Here is the error log.
这是错误日志。 I've even tried easy_installing libxml2, I'm not sure how to proceed.
我什至尝试过easy_installing libxml2,我不知道如何继续。

I had the same problem, albeit using WinPython 64bit 2.7.3.1.我遇到了同样的问题,尽管使用的是 WinPython 64bit 2.7.3.1。
I solved it using the precompiled installer which can be found here: https://pypi.python.org/pypi/lxml/3.3.3#downloads我使用预编译的安装程序解决了它,可以在这里找到: https ://pypi.python.org/pypi/lxml/3.3.3#downloads
Directly installing the package by running the .exe failed, because the installer could not find my python installation (altough it is registered).通过运行 .exe 直接安装包失败,因为安装程序找不到我的 python 安装(尽管它已注册)。 However, I then successfully used the WinPython Control Panel to install the package!
但是,我随后成功使用 WinPython 控制面板安装了该软件包!
edit: before that, I tried various things which I found on stackoverflow, including installing some Visual C++ (Python) compilers but none of that worked.编辑:在此之前,我尝试了在 stackoverflow 上找到的各种东西,包括安装一些 Visual C++ (Python) 编译器,但都没有奏效。
I had the same problem using Python 64bit 2.7.11 on Windows 10.我在 Windows 10 上使用 Python 64bit 2.7.11 时遇到了同样的问题。
After I tried installing scrapy using pip
many times, I had success as follow:在我多次尝试使用
pip
安装 scrapy 后,我取得了如下成功:
First I installed precompiled package lxml v3.6.0
from .exe
file.首先,我从
.exe
文件安装了预编译包lxml v3.6.0
。 It can be found here https://pypi.python.org/pypi/lxml/3.6.0 .它可以在这里找到https://pypi.python.org/pypi/lxml/3.6.0 。
Finally, I ran pip install scrapy
again and installation ended successful.最后,我再次运行
pip install scrapy
并安装成功。
Happy hacking !!!快乐黑客!
I couldn't use PYPY to install the package normally however I could use normal pip.我无法使用 PYPY 正常安装软件包,但是我可以使用普通的 pip。 So I went to my file system and took the lxml files from python39>lib and copy pasted them into my pypy>lib file.
所以我去了我的文件系统并从 python39>lib 中取出 lxml 文件并将它们复制粘贴到我的 pypy>lib 文件中。 The files are: lxml lxml-4.8.0.dist-info
这些文件是: lxml lxml-4.8.0.dist-info
