在python中安装lxml模块

Question

在运行python脚本时,我遇到了这个错误

  from lxml import etree
ImportError: No module named lxml

现在我尝试安装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的构建配置

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

Answer 1

做就是了:

sudo apt-get install python-lxml

如果您打算从源代码安装,那么albertov的回答将有所帮助.但除非有原因,否则,只需从存储库中安装它.

Answer 2

我解决了升级lxml版本的问题:

pip install --upgrade lxml

Answer 3

你需要安装Python的头文件(debian/ubuntu中的python-dev包)来编译lxml.与libxml2,libxslt,libxml2-dev和libxslt-dev一样:

apt-get install python-dev libxml2 libxml2-dev libxslt-dev

Answer 4

如果您正在运行python3,则必须执行以下操作:

pip3 install lxml

Answer 5

对于 RHEL/CentOS，运行“python --version”命令来查找 Python 版本。例如下面：

$ python --version 
  Python 2.7.12

现在运行“sudo yum search lxml”来找出 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

现在您可以根据您的 Python 版本选择包并运行如下命令：

$ sudo yum install python27-lxml.x86_64

Answer 6

对于python 3，这对我有用

sudo apt-get install python3-lxml
