在python中安装lxml模块
当运行一个python脚本时，我得到了这个错误
from lxml import etree ImportError: No module named lxml 现在我试图安装lxml
sudo easy_install lmxl
但它给了我以下错误
Building lxml version 2.3.beta1. NOTE: Trying to build without Cython, pre-generated 'src/lxml/lxml.etree.c' needs to be available. ERROR: /bin/sh: xslt-config: not found ** make sure the development packages of libxml2 and libxslt are installed **
使用libxslt的构buildconfiguration
src/lxml/lxml.etree.c:4: fatal error: Python.h: No such file or directory compilation terminated. error: Setup script exited with error: command 'gcc' failed with exit status 1
做就是了：
sudo apt-get install python-lxml
如果你打算从源代码安装，那么albertov的答案将有所帮助。 但是，除非有理由，否则，只需从存储库安装它。
你需要安装Python的头文件（debian / ubuntu中的python-dev包）来编译lxml。 以及libxml2，libxslt，libxml2-dev和libxslt-dev：
apt-get install python-dev libxml2 libxml2-dev libxslt-dev
我解决了升级lxml版本：
pip install --upgrade lxml
如果你正在运行python3，你必须这样做：
pip3 install lxml
对于RHEL / CentOS，运行“python –version”命令查找Python版本。 例如下面：
$ python --version Python 2.7.12
现在运行“sudo yum search lxml”找出python * -lxml包。
$ sudo yum search lxml Failed to set locale, defaulting to C Loaded plugins: priorities, update-motd, upgrade-helper 1014 packages excluded due to repository priority protections ============================================================================================================= N/S matched: lxml ============================================================================================================= python26-lxml-docs.noarch : Documentation for python-lxml python27-lxml-docs.noarch : Documentation for python-lxml python26-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt python27-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt
现在你可以根据你的Python版本来select软件包，像下面这样运行命令：
$ sudo yum install python27-lxml.x86_64
